ASHR2 Antibody

What is ASH2L and why is it important in epigenetic research?

ASH2L (Absent, Small, or Homeotic-like 2) is a 628 amino acid protein that contains a nuclear localization signal and PHD finger motif, suggesting its function as a transcription regulator. The gene encodes two isoforms through alternative splicing: ASH2L1 (the full-length protein) and ASH2L2 (missing the first 94 amino acid residues found in ASH2L1) . ASH2L shares approximately 60% homology with Drosophila ash2, which positively regulates expression of certain genes in early development . It is particularly important in epigenetic research because it forms part of histone methyltransferase complexes that regulate chromatin structure and gene expression.

ASH2L is highly expressed in specific tissues including fetal liver, testis, and leukemia cell lines with erythroid and megakaryocytic potential (such as K562, Hel, and Dami), suggesting its importance in development and potential roles in certain malignancies . Its involvement in epigenetic regulation makes it a critical target for researchers investigating transcriptional control, development, and disease mechanisms.

What applications are ASH2L antibodies most commonly used for?

• Western blotting to detect ASH2L protein expression levels in cell or tissue lysates

• Chromatin immunoprecipitation (ChIP) assays to identify ASH2L-associated genomic regions

• Immunoprecipitation (IP) to study protein-protein interactions

• Immunofluorescence to visualize subcellular localization of ASH2L

When selecting an ASH2L antibody, researchers should verify the specific applications validated by the manufacturer and consider performing preliminary validation experiments to confirm suitability for their particular experimental system.

How should I validate the specificity of an ASH2L antibody for my research?

Validating antibody specificity is critical for ensuring reliable research results. For ASH2L antibodies, consider the following validation approaches:

• Positive and negative controls: Use cell lines known to express (e.g., K562, Hel, Dami) or not express ASH2L .

• Multiple detection methods: Verify results using complementary techniques (e.g., if using IHC, confirm with Western blot).

• Peptide competition assay: Pre-incubate the antibody with the immunizing peptide prior to application to confirm specific binding.

• Genetic approaches: Use ASH2L knockdown or knockout samples as negative controls. The signal should be significantly reduced or eliminated in these samples.

• Cross-reactivity testing: Test the antibody against related proteins, particularly if working with models where homologs exist.

For recombinant antibodies, reviewing the structural information and production method can provide additional confidence in specificity. When possible, compare results from multiple antibodies targeting different epitopes of ASH2L to further validate findings.

What is the recommended sample preparation protocol for detecting ASH2L in Western blots?

When preparing samples for detecting ASH2L in Western blots, researchers should follow these methodological steps:

• Lysis buffer selection: Use RIPA buffer (50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1% NP-40, 0.5% sodium deoxycholate, 0.1% SDS) supplemented with protease inhibitors to efficiently extract nuclear proteins.

• Sample preparation:

  • For cell lines: Harvest 1-5 × 10^6 cells and lyse in 300-500 μL lysis buffer

  • For tissues: Homogenize 20-50 mg tissue in 500-1000 μL lysis buffer

• Protein denaturation: Heat samples at 95°C for 5 minutes in Laemmli buffer containing DTT or β-mercaptoethanol.

• Gel selection: Use 8-10% SDS-PAGE gels to achieve optimal separation of ASH2L (expected MW: ~70 kDa).

• Transfer conditions: Transfer to PVDF membrane at 100V for 60-90 minutes in standard transfer buffer.

• Blocking: Block with 5% non-fat dry milk in TBST for 1 hour at room temperature.

• Antibody incubation: Dilute primary antibody according to manufacturer recommendations (typically 1:1000 to 1:2000) and incubate overnight at 4°C.

For optimal results, include positive control samples such as lysates from cell lines known to express ASH2L (e.g., K562) . When troubleshooting, consider that nuclear proteins like ASH2L may require more rigorous extraction methods than cytoplasmic proteins.

How can I optimize chromatin immunoprecipitation (ChIP) protocols for ASH2L antibodies?

Optimizing ChIP protocols for ASH2L antibodies requires careful consideration of several parameters given ASH2L's role as a nuclear protein involved in chromatin regulation:

• Crosslinking optimization: Since ASH2L is part of protein complexes that interact with chromatin, a dual crosslinking approach is recommended:

  • Perform protein-protein crosslinking with DSG (disuccinimidyl glutarate, 2 mM) for 30 minutes at room temperature

  • Follow with standard formaldehyde crosslinking (1% for 10 minutes)

• Chromatin fragmentation:

  • For sonication: 10-15 cycles (30 seconds ON/30 seconds OFF) to achieve fragments of 200-500 bp

  • For enzymatic shearing: Optimize digestion time with micrococcal nuclease (MNase)

• Antibody selection and validation:

  • Use antibodies validated specifically for ChIP applications

  • Perform preliminary IP experiments to confirm the antibody's ability to pull down ASH2L

  • Consider using antibodies targeting different epitopes to validate findings

• Blocking and pre-clearing:

  • Use 1-2 μg of antibody per 25-30 μg of chromatin

  • Pre-clear chromatin with protein A/G beads before adding the antibody

  • Include IgG controls matched to the host species of the ASH2L antibody

• Washing stringency:

  • Employ increasingly stringent washing buffers (low salt, high salt, LiCl, TE)

  • Monitor signal-to-noise ratio and adjust washing conditions accordingly

• Elution and reverse crosslinking:

  • Elute at 65°C with SDS-containing buffer

  • Reverse crosslinks overnight at 65°C

For ChIP-seq applications, additional quality control steps should include library preparation with adequate controls and verification of enrichment by qPCR at known target genes before sequencing.

What are the key considerations when using ASH2L antibodies for co-immunoprecipitation of protein complexes?

ASH2L participates in multiprotein complexes, making co-immunoprecipitation (co-IP) a valuable approach for studying its interactions. Key methodological considerations include:

• Lysis conditions:

  • Use gentler lysis buffers (e.g., 20 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% NP-40, 2 mM EDTA) supplemented with protease inhibitors

  • Avoid harsh detergents that might disrupt protein-protein interactions

  • Include phosphatase inhibitors to preserve phosphorylation-dependent interactions

• Nuclear extraction:

  • Since ASH2L is primarily nuclear, employ nuclear extraction kits or protocols

  • Consider using specialized nuclear complex co-IP buffers containing low concentrations of detergents

• Antibody orientation:

  • Consider both direct approaches (using anti-ASH2L antibodies) and reverse co-IP (using antibodies against suspected interaction partners)

  • Use 2-5 μg antibody per 500 μg protein extract

• Controls:

  • Include isotype-matched IgG controls

  • Consider input samples (5-10% of starting material)

  • Include known interaction partners as positive controls

  • Use ASH2L-depleted samples as negative controls

• Detection methods:

  • Western blotting with antibodies against known or suspected interaction partners

  • Consider mass spectrometry for unbiased identification of novel interactions

  • For confirmation, perform reciprocal co-IPs with antibodies against interaction partners

By optimizing these parameters, researchers can effectively capture and analyze ASH2L-containing protein complexes, providing insights into its functional roles in transcriptional regulation and epigenetic modifications.

How do I interpret conflicting results when comparing different ASH2L antibodies?

When faced with conflicting results from different ASH2L antibodies, systematic troubleshooting and comparative analysis are essential:

• Epitope mapping analysis:

  • Compare the epitope regions targeted by each antibody

  • Antibodies targeting different domains may yield different results due to:

    • Epitope masking in protein complexes

    • Conformational changes affecting epitope accessibility

    • Post-translational modifications near the epitope region

• Isoform specificity assessment:

  • Determine if antibodies can distinguish between ASH2L1 and ASH2L2 isoforms

  • The shorter isoform (ASH2L2) lacks the first 94 amino acids, so antibodies targeting this region will only detect ASH2L1

  • Verify which isoforms are expressed in your experimental system

• Validation experiments:

  • Perform knockdown/knockout experiments with each antibody

  • Use recombinant ASH2L proteins as positive controls

  • Conduct peptide competition assays to confirm specificity

• Cross-reactivity investigation:

  • Check for potential cross-reactivity with related proteins

  • Review the validation data provided by manufacturers

  • Consider spectral unmixing for fluorophores with overlapping spectra

• Multi-parametric flow cytometry:

  • Optimize compensation when including ASH2L with other nuclear markers

  • Include proper FMO (fluorescence minus one) controls

  • Consider using metal-conjugated antibodies for mass cytometry (CyTOF) to expand multiplexing capacity

• Co-immunoprecipitation sequential approaches:

  • Perform tandem immunoprecipitation to isolate complexes containing multiple markers

  • Elute under native conditions after first IP, then perform second IP

  • Analyze by Western blot or mass spectrometry

• Chromatin studies:

  • For sequential ChIP (re-ChIP), optimize elution conditions between immunoprecipitations

  • Consider CUT&RUN or CUT&Tag approaches for improved sensitivity

  • Implement ChIP-seq with multiple antibodies in parallel with integrative bioinformatic analysis

When designing multiplexed experiments, carefully validate each antibody individually before combining them, and include appropriate single-stained controls to ensure accurate interpretation of results.

How can I address non-specific binding when using ASH2L antibodies?

Non-specific binding is a common challenge when working with antibodies for nuclear proteins like ASH2L. Here are methodological approaches to address this issue:

• Optimization of blocking conditions:

  • Test different blocking agents (BSA, non-fat milk, normal serum, commercial blockers)

  • Extend blocking time (2-3 hours at room temperature or overnight at 4°C)

  • Add 0.1-0.5% Triton X-100 or Tween-20 to blocking buffer to reduce hydrophobic interactions

  • Perform titration experiments to identify optimal antibody concentration

  • Consider using higher dilutions combined with longer incubation times

  • For Western blots, test dilutions between 1:500 and 1:5000

• Pre-adsorption techniques:

  • Pre-incubate antibody with tissues or cells from species not expressing the target

  • Use tissue powder from non-expressing samples for pre-adsorption

  • Consider commercial antibody pre-adsorption kits

• Buffer modifications:

  • Increase salt concentration in wash buffers (up to 500 mM NaCl)

  • Add low concentrations of SDS (0.1-0.2%) to wash buffers

  • Include competing proteins (e.g., 0.1-1% BSA) in antibody dilution buffer

• Sample preparation refinements:

  • Ensure complete blocking of endogenous peroxidases for IHC applications

  • Optimize antigen retrieval methods (heat-induced vs. enzymatic)

  • Test different fixation methods and durations

By systematically implementing these strategies, researchers can significantly reduce non-specific binding and improve the signal-to-noise ratio when using ASH2L antibodies across different applications.
