YDL085C-A Antibody

What is the YDL085C-A protein and why is it studied in yeast research?

YDL085C-A is a SERF-like protein in yeast with a sequence of 68 amino acids: MARGNQRDLARQKNLKKQKDMAKNQKKSGDPKKRMESDAEILRQKQAAADARREAEKLEKLKAEKTRR . This protein belongs to a family of small SERF (Small EDRK-Rich Factor) proteins that are found across eukaryotes. In research contexts, YDL085C-A is studied primarily to understand its function in yeast cellular processes and as a model for understanding similar proteins in higher organisms. The relatively small size and the high content of basic amino acids (lysine and arginine) suggest potential roles in nucleic acid binding or protein-protein interactions. Methodologically, researchers typically approach the study of this protein through knockout/knockdown experiments, localization studies, and protein-protein interaction analyses using the antibodies specific to different regions of the protein.

What are the available YDL085C-A antibody variants and their target regions?

There are three primary antibody combinations available for YDL085C-A (Q3E7B7) research, each targeting different regions of the protein:

All three antibody combinations have an ELISA titer of approximately 10,000, corresponding to detection sensitivity of about 1 ng of target protein in Western blot applications . When designing experiments, researchers should consider which region of the protein is most accessible in their experimental context or which domain is most relevant to their specific research question.

How should researchers validate YDL085C-A antibodies before experimental use?

Antibody validation is a crucial step before using YDL085C-A antibodies in experiments. Following established validation protocols similar to those recommended by the International Working Group on Antibody Validation (IWGAV) , researchers should:

• Perform positive and negative controls using YDL085C-A knockout/knockdown yeast strains to confirm specificity

• Test cross-reactivity with related proteins to ensure selectivity

• Verify epitope recognition through peptide competition assays

• Establish optimal working concentrations through titration experiments

• Confirm reproducibility across different lots of the antibody

For YDL085C-A specifically, testing against wild-type and knockout strains provides the most definitive validation. Western blotting should show a band at the expected molecular weight (approximately 7.5 kDa based on its 68 amino acid sequence) in wild-type samples that is absent in knockout samples . Given that YDL085C-A falls into the "Hard" AbClass category, validation is particularly important to ensure experimental reliability .

What are the recommended experimental conditions for Western blotting with YDL085C-A antibodies?

For Western blot applications using YDL085C-A antibodies, researchers should consider the following optimized conditions:

• Sample preparation: Extract proteins from yeast cells using either glass bead lysis or enzymatic cell wall disruption followed by gentle detergent lysis.

• Protein denaturation: Heat samples at 95°C for 5 minutes in a reducing sample buffer containing SDS and DTT.

• Gel selection: Use high-percentage (15-20%) SDS-PAGE gels or specialized Tricine-SDS-PAGE systems optimized for small proteins, as YDL085C-A is only 68 amino acids (approximately 7.5 kDa).

• Transfer conditions: Use PVDF membranes with 0.2 μm pore size (rather than 0.45 μm) and transfer at lower voltage (30V) for longer time (2 hours) to ensure efficient transfer of small proteins.

• Blocking: Use 5% non-fat dry milk or BSA in TBST for 1 hour at room temperature.

• Primary antibody incubation: Dilute the selected YDL085C-A antibody (X-Q3E7B7-N, -C, or -M) to a working concentration based on the ELISA titer of 10,000, typically starting at 1:1000 dilution .

• Detection system: Use an HRP-conjugated secondary antibody with enhanced chemiluminescence for optimal sensitivity.

These conditions may require optimization depending on specific experimental setups and the particular antibody combination being used.

How can researchers overcome epitope masking issues when detecting YDL085C-A in complex with other proteins?

Epitope masking can significantly hinder the detection of YDL085C-A when it is engaged in protein-protein interactions. To address this challenge:

• Employ multiple antibody combinations targeting different regions (N-terminus, C-terminus, and middle region) to increase the likelihood of accessing at least one unmasked epitope .

• Modify immunoprecipitation protocols to include gentle crosslinking (0.1-0.5% formaldehyde for 10 minutes) to stabilize complexes while maintaining antibody accessibility.

• Use denaturing conditions selectively to disrupt protein-protein interactions without compromising epitope structure.

• Consider native gel electrophoresis followed by Western blotting to identify complexes containing YDL085C-A.

• Implement proximity ligation assays (PLA) to detect YDL085C-A in close proximity to interacting partners without requiring direct epitope binding in the interaction interface.

The complementary use of different antibodies (X-Q3E7B7-N, -C, and -M) provides a strategic approach to addressing epitope masking, as interactions involving YDL085C-A may leave certain regions of the protein accessible while masking others .

What are the optimal strategies for detecting post-translational modifications of YDL085C-A?

Detecting post-translational modifications (PTMs) on YDL085C-A requires specialized approaches:

• Phosphorylation analysis:

  • Enrich phosphorylated proteins using phospho-specific affinity methods (TiO₂ or IMAC)

  • Use Phos-tag™ SDS-PAGE to separate phosphorylated from non-phosphorylated forms

  • Combine with lambda phosphatase treatment as a negative control

• Ubiquitination detection:

  • Express epitope-tagged ubiquitin in yeast

  • Use denaturing conditions during lysis to preserve ubiquitin modifications

  • Immunoprecipitate with YDL085C-A antibodies and probe for ubiquitin

• Other PTMs:

  • For methylation, acetylation, or SUMOylation, combine immunoprecipitation with YDL085C-A antibodies followed by PTM-specific antibody detection

  • Verify with mass spectrometry for precise modification site mapping

• Antibody selection considerations:

  • When studying PTMs, carefully select YDL085C-A antibodies whose epitopes do not contain potential modification sites

  • The X-Q3E7B7-N, X-Q3E7B7-C, and X-Q3E7B7-M antibodies target different regions, allowing flexibility in choosing antibodies that don't interfere with the PTM being studied

This methodological approach ensures comprehensive analysis of YDL085C-A modifications that may be critical to understanding its function in cellular contexts.

• Signal verification:

  • Confirm specificity using YDL085C-A knockout strains as negative controls
