RPS6KA6 Antibody, Biotin conjugated

What is RPS6KA6 and what biological functions does it serve in research contexts?

RPS6KA6 (Ribosomal Protein S6 Kinase, 90kDa, Polypeptide 6), also known as RSK4, p90RSK6, and pp90RSK4, is a constitutively active serine/threonine-protein kinase that exhibits growth-factor-independent kinase activity. This protein participates in p53/TP53-dependent cell growth arrest signaling pathways and appears to play an inhibitory role during embryogenesis . The gene is identified with Gene ID 27330 and Swiss-Prot accession number Q9UK32 . Understanding RPS6KA6 function is particularly important in research involving cell growth regulation, cancer biology, and developmental processes. When designing experiments targeting this protein, researchers should consider its role in signaling networks and potential interactions with tumor suppressor pathways.

What are the specific applications of biotin-conjugated RPS6KA6 antibodies compared to other detection formats?

Biotin-conjugated RPS6KA6 antibodies have demonstrated efficacy across multiple experimental techniques:

The biotin conjugation provides significant signal amplification advantages through secondary detection with streptavidin systems while maintaining high specificity for the RPS6KA6 target . This format is particularly valuable for detecting low-abundance targets or when working with challenging sample types that may contain inhibitory factors affecting antibody binding.

How do storage conditions affect the stability and performance of biotin-conjugated RPS6KA6 antibodies?

Optimal storage conditions are critical for maintaining antibody performance over time. For biotin-conjugated RPS6KA6 antibodies, the recommended storage temperature is -20°C, which preserves stability for approximately 12 months . The antibody is typically supplied in a protective buffer containing glycerol (50%), which prevents freeze-thaw damage, along with buffering agents and preservatives. In the case of catalog number bsm-62066r-biotin, the storage buffer contains 0.01M TBS (pH 7.4) with 1% BSA, 0.02% Proclin300, and 50% Glycerol . Similar formulations are found in other commercial preparations, such as ABIN7168193, which contains 0.03% Proclin 300, 50% Glycerol, and 0.01M PBS at pH 7.4 .

To maintain antibody performance, researchers should aliquot the antibody upon receipt to minimize freeze-thaw cycles, as repeated freezing and thawing can lead to protein denaturation and loss of binding activity. Each aliquot should be thawed only once and maintained at 4°C during experimental procedures, then returned to -20°C for long-term storage if unused portion remains.

What are the optimal sample preparation protocols when using biotin-conjugated RPS6KA6 antibodies for Western blotting?

When preparing samples for Western blotting with biotin-conjugated RPS6KA6 antibodies, researchers should follow these methodological steps for optimal results:

• Lysate Preparation: Extract proteins using a buffer containing protease and phosphatase inhibitors, particularly important when studying kinases like RPS6KA6.

• Sample Quantification: Standardize protein loading (20-50 μg total protein recommended) using BCA or Bradford assays.

• Electrophoresis Conditions: Use 8-10% polyacrylamide gels as RPS6KA6 has a molecular weight of approximately 90 kDa.

• Transfer Parameters: Optimize transfer conditions using PVDF membranes (preferred over nitrocellulose for phospho-proteins).

• Blocking Strategy: Block with 5% BSA in TBST rather than milk, as milk contains phospho-proteins that may interfere with detection.

• Antibody Dilution: Start with 1:1000 dilution for the biotin-conjugated RPS6KA6 antibody, then optimize based on signal intensity .

• Detection System: Use streptavidin-HRP or streptavidin-fluorescent conjugates for detection, with signal development times optimized empirically.

Performing a titration experiment with different antibody concentrations (1:300, 1:1000, 1:3000) is recommended to determine the optimal dilution that provides specific signal with minimal background for your specific sample type .

How should researchers optimize immunohistochemistry protocols when using biotin-conjugated RPS6KA6 antibodies?

When performing immunohistochemistry with biotin-conjugated RPS6KA6 antibodies, the following protocol optimizations are recommended:

For Paraffin-Embedded Sections (IHC-P):

• Antigen Retrieval: Heat-induced epitope retrieval using citrate buffer (pH 6.0) for 15-20 minutes is recommended, as this helps expose the epitopes masked by fixation.

• Endogenous Biotin Blocking: Critical when using biotin-conjugated antibodies; block endogenous biotin using a commercial biotin blocking kit prior to antibody incubation.

• Antibody Dilution: Begin with 1:200-400 dilution range as recommended for IHC-P applications .

• Incubation Conditions: Optimal results are typically achieved with overnight incubation at 4°C in a humidified chamber.

• Detection System: Use streptavidin-HRP followed by DAB or other chromogenic substrates, avoiding ABC kits which may produce higher background due to the biotin conjugation already present on the primary antibody.

For Frozen Sections (IHC-F):

• Fixation: Brief post-sectioning fixation with 4% paraformaldehyde for 10 minutes.

• Permeabilization: Include a permeabilization step with 0.1-0.3% Triton X-100 for improved antibody penetration.

• Antibody Dilution: Use the more dilute 1:100-500 range as recommended for IHC-F applications .

A methodological validation using both positive and negative controls is essential, particularly human tissue samples known to express RPS6KA6, alongside appropriate technical controls to confirm the specificity of the staining pattern observed.

How can researchers validate the specificity of biotin-conjugated RPS6KA6 antibodies in their experimental systems?

Rigorous validation of antibody specificity is critical for generating reliable research data. For biotin-conjugated RPS6KA6 antibodies, implement the following validation strategies:

• Epitope Analysis: Confirm that the antibody targets the specific region of RPS6KA6 needed for your study. Available antibodies target different epitopes, including:

  • AA 15-45 (N-terminal region)

  • AA 340-467 (middle region)

  • AA 636-745 (C-terminal region) (referenced in comparative listings)

  • C-terminal region (specific amino acids not defined)

• Knockdown/Knockout Controls: Perform RPS6KA6 siRNA knockdown or CRISPR knockout experiments, comparing antibody staining patterns between wild-type and knockdown/knockout samples.

• Overexpression Controls: Overexpress RPS6KA6 in a cell line with low endogenous expression and verify increased antibody signal.

• Cross-Reactivity Assessment: Test the antibody against related RSK family members (RSK1, RSK2, RSK3) to ensure specificity for RSK4/RPS6KA6.

• Peptide Competition: Pre-incubate the antibody with the immunizing peptide prior to staining to demonstrate signal abolishment.

• Multiple Antibody Comparison: Compare results using antibodies that recognize different epitopes of RPS6KA6 to confirm consistent detection patterns.

• Mass Spectrometry Validation: Perform immunoprecipitation followed by mass spectrometry to confirm capture of RPS6KA6 protein.

These validation approaches should be documented thoroughly in research publications to support the reliability of experimental findings.

What are the considerations for using biotin-conjugated RPS6KA6 antibodies in multiplex immunostaining experiments?

When designing multiplex immunostaining experiments incorporating biotin-conjugated RPS6KA6 antibodies, researchers should address several technical considerations:

• Streptavidin Detection Strategy: Select a streptavidin conjugate (fluorophore, enzyme) with minimal spectral overlap with other detection systems being used.

• Staining Sequence Optimization: For multi-color immunofluorescence:

  • Begin with the weakest signal (often the biotin-conjugated antibody)

  • Apply streptavidin detection before proceeding to subsequent antibodies

  • Include stringent washing steps between antibody applications

• Blocking Endogenous Biotin: Critical in biotin-rich tissues (liver, kidney, brain); use commercial biotin blocking kits before antibody application.

• Cross-reactivity Prevention: When using antibodies from the same host species (rabbit anti-RPS6KA6 biotin with other rabbit antibodies), employ sequential immunostaining with monovalent Fab fragment blocking between staining steps.

• Antigen Denaturation Risk: Consider that some detection methods may denature antigens needed for subsequent staining; fluorescent streptavidin conjugates typically present lower risk than enzymatic methods.

• Signal Amplification Balance: Biotin-streptavidin systems provide significant amplification, which may overwhelm other signals in multiplex experiments; optimize dilutions accordingly.

A pilot study comparing single staining versus multiplex protocols is recommended to identify potential interference issues before proceeding with full experimental design.

How does epitope specificity of different RPS6KA6 antibodies impact experimental outcomes in signaling pathway studies?

The choice of epitope specificity in RPS6KA6 antibodies significantly impacts experimental outcomes, particularly in studies of signaling pathway activation and protein interactions:

The biotin-conjugated antibody targeting AA 340-467 (ABIN7168193) provides middle region specificity, potentially detecting RPS6KA6 regardless of activation state. This makes it suitable for general detection purposes, though researchers investigating specific phosphorylation events or protein interactions should carefully consider whether this epitope region may be masked or modified under their experimental conditions.

For studies focusing on RPS6KA6's role in p53/TP53-dependent cell growth arrest signaling, antibodies detecting the active conformation may provide more relevant information than those detecting total protein levels. Researchers should select the epitope specificity that aligns with their specific research question and validate the selected antibody's ability to detect the relevant protein state.

What are common sources of background when using biotin-conjugated RPS6KA6 antibodies and how can they be mitigated?

Background issues when using biotin-conjugated RPS6KA6 antibodies typically arise from several methodological factors, each requiring specific mitigation strategies:

• Endogenous Biotin: Particularly problematic in biotin-rich tissues:

  • Solution: Implement dedicated biotin blocking steps using commercial kits before antibody application

  • Method: Sequential incubation with avidin followed by biotin effectively neutralizes endogenous biotin

• Endogenous Peroxidase Activity: Relevant when using HRP-streptavidin detection:
