BHLH75 Antibody

What are the recommended storage conditions for BHLH family antibodies to maintain optimal activity?

BHLH family antibodies should be maintained at 2-8°C for short-term storage (up to 2 weeks) in their original buffer conditions. For long-term storage, it is recommended to store the antibodies at -20°C in small aliquots to prevent freeze-thaw cycles that can compromise antibody functionality . This approach minimizes protein degradation and preserves epitope recognition capabilities over extended periods. When preparing aliquots, use sterile conditions and consider adding protein stabilizers if the antibody concentration is below 0.5 mg/ml.

What applications are BHLH family antibodies most commonly used for in research settings?

BHLH family antibodies are typically validated for multiple applications including Western Blot (WB), Immunohistochemistry on paraffin-embedded tissues (IHC-P), and Flow Cytometry (FC) . The recommended dilutions for these applications vary:

• Western Blot: 1:1000 dilution

• IHC-P: 1:50-1:100 dilution

• Flow Cytometry: 1:10-1:50 dilution

These applications allow researchers to investigate expression patterns, protein localization (predominantly nuclear for BHLH transcription factors), and quantitative analysis of protein levels across different experimental conditions.

How do I determine cross-reactivity of BHLH antibodies with related family members?

Cross-reactivity assessment is essential for BHLH antibodies due to the high homology between family members. Begin by examining the immunogen sequence used to generate the antibody against sequence alignments of related BHLH proteins. For BHLHE22 antibody, for example, the immunogen consists of a KLH-conjugated synthetic peptide corresponding to amino acids 236-264 from the central region .

Experimentally, validate specificity through:

• Western blot analysis using recombinant proteins of multiple BHLH family members

• Immunoprecipitation followed by mass spectrometry to identify all bound proteins

• Cell lines with knockdown/knockout of the target protein as negative controls

• Comparative analysis across species with known sequence homology (e.g., human, mouse, and chicken for BHLHE22)

What are the most reliable validation methods to confirm BHLH antibody specificity?

A multi-step validation approach is recommended for confirming BHLH antibody specificity:

• Expression Correlation: Compare protein detection with known mRNA expression patterns (e.g., brain-specific expression with highest levels in cerebellum for BHLHE22)

• Orthogonal Validation: Use alternative antibodies targeting different epitopes of the same protein and compare results

• Genetic Validation: Test antibody in cells where the target gene has been knocked out or knocked down

• Independent Approach Validation: Compare results from antibody-based detection with other methods such as mass spectrometry

• Biophysical Characterization: Consider isothermal titration calorimetry to characterize binding events and affinity

Research indicates that $0.375 to $1.75 billion is wasted yearly on non-specific antibodies, highlighting the critical importance of thorough validation . A scaled validation procedure should address both specificity and sensitivity across intended applications.

How can I optimize immunoprecipitation protocols for nuclear proteins like BHLH transcription factors?

Optimizing immunoprecipitation (IP) of BHLH transcription factors requires specific considerations:
