The sxa2 Antibody is a research-grade antibody developed for detection of specific protein targets in experimental systems. Similar to other research antibodies like SOX2 antibodies, sxa2 Antibody recognizes specific epitopes within its target protein structure. The specificity of antibody-epitope binding determines the utility of the antibody in various research applications. For optimal experimental design, researchers should note that antibody-epitope interactions may be influenced by protein conformational changes, post-translational modifications, and experimental conditions that can affect epitope accessibility .

What are the recommended applications for sxa2 Antibody in molecular biology research?

Based on validation studies, sxa2 Antibody can be employed in multiple molecular biology techniques including ELISA, western blotting, immunofluorescence, and immunohistochemistry. Each application requires specific optimization parameters. For ELISA applications, researchers typically use dilution ranges between 1:100 and 1:1000, depending on antibody concentration and detection sensitivity requirements. When utilizing semi-automated ELISA methods, samples are typically diluted (1 in 110) and allowed to react with immobilized target proteins at varying concentrations, commonly between 1.6 and 160 nM, to establish dose-response relationships .

How does sxa2 Antibody compare with other antibodies targeting similar protein families?

When comparing antibody performance across protein families, researchers should consider cross-reactivity profiles, sensitivity thresholds, and application-specific performance metrics. Similar to how SOX1 and SOX2 antibodies share significant sequence homology primarily through the high mobility group (HMG) box, a 79 amino acid DNA-binding domain, sxa2 Antibody may exhibit cross-reactivity with structurally similar proteins . This characteristic requires careful validation through multiple detection methods. Researchers should validate antibody specificity using techniques such as western blotting with recombinant protein targets and knockout/knockdown controls to ensure target specificity.

• Immunoprecipitation: Incubate chromatin with 3-5 μg of sxa2 Antibody overnight at 4°C

• DNA purification and analysis: Reverse crosslinks, purify DNA, and analyze by qPCR or sequencing

When analyzing ChIP-seq data, implement computational pipelines that account for binding site distribution patterns, peak enrichment significance, and motif analysis to identify consensus binding sequences.

What are the optimal fixation and permeabilization conditions for sxa2 Antibody in immunocytochemistry?

Optimal fixation and permeabilization conditions for sxa2 Antibody in immunocytochemistry depend on the cellular localization of the target protein. For intranuclear proteins (similar to SOX2), the following protocol is recommended:

• Fixation: 4% paraformaldehyde for 15 minutes at room temperature

• Permeabilization: 0.1-0.5% Triton X-100 for 10 minutes

• Blocking: 5% normal serum (matching secondary antibody host) for 1 hour

• Primary antibody: Dilute sxa2 Antibody 1:100-1:500 in blocking buffer, incubate overnight at 4°C

• Detection: Use appropriate fluorophore-conjugated secondary antibody

If the target protein exhibits dual localization patterns (nuclear and cytoplasmic) as observed with some SOX2 proteins in adult stem cells, modification of permeabilization conditions may be necessary to preserve cytoplasmic staining without compromising nuclear signal .

How should researchers validate the specificity of sxa2 Antibody in their experimental systems?

Comprehensive validation of sxa2 Antibody specificity requires a multi-method approach:

This systematic approach mirrors validation methods used for other research antibodies, where confirmatory testing across multiple laboratories may be necessary to resolve discrepant results .

What are the recommended protocols for quantifying sxa2 Antibody binding in ELISA-based assays?

For quantitative ELISA using sxa2 Antibody, implement the following methodological approach:
