BHLH23 Antibody

What is BHLH23 and why is it significant in plant research?

BHLH23 belongs to the basic helix-loop-helix family of transcription factors that regulate crucial developmental processes in Arabidopsis thaliana. The significance of this protein lies in its role in transcriptional regulation of plant development, stress responses, and metabolic processes. Researchers utilize BHLH23 Antibody to elucidate protein expression patterns, subcellular localization, and interaction networks with other transcription factors and regulatory elements .

What are the optimal storage conditions for maintaining BHLH23 Antibody activity?

For maintaining optimal BHLH23 Antibody activity, researchers should adhere to the following storage protocol:

• Store antibody aliquots at -20°C for long-term preservation

• Avoid repeated freeze-thaw cycles by preparing single-use aliquots

• For short-term use (1-2 weeks), storage at 4°C is acceptable

• Add glycerol (final concentration 50%) for cryoprotection if extended storage is necessary

• Maintain sterile conditions and use appropriate preservatives (0.02% sodium azide) for diluted working solutions

Proper storage significantly impacts antibody performance in experimental applications such as Western blotting, immunoprecipitation, and immunohistochemistry .

How can I validate the specificity of BHLH23 Antibody in my experimental system?

Validation of BHLH23 Antibody specificity requires a multi-faceted approach:

• Control samples validation:

  • Test with positive control (wild-type Arabidopsis tissue expressing BHLH23)

  • Use negative controls (BHLH23 knockout or knockdown lines)

  • Include secondary antibody-only controls to assess non-specific binding

• Cross-reactivity assessment:

  • Test against recombinant BHLH23 protein

  • Evaluate potential cross-reactivity with related BHLH family members (BHLH30, BHLH35, BHLH47)

  • Perform peptide competition assays using the immunizing peptide

• Multi-technique confirmation:

  • Compare signal patterns across Western blotting, immunofluorescence, and ELISA

  • Correlate protein detection with mRNA expression data

  • Verify molecular weight matches theoretical prediction for BHLH23

This systematic approach ensures the observed signals truly represent BHLH23 protein rather than experimental artifacts .

How can I optimize BHLH23 Antibody performance for low-abundance protein detection?

Optimizing BHLH23 Antibody for detecting low-abundance proteins requires advanced methodological refinements:

• Sample preparation enhancements:

• Signal amplification strategies:

  • Employ tyramide signal amplification (TSA) for immunohistochemistry

  • Utilize highly sensitive chemiluminescent substrates for Western blotting

  • Optimize primary antibody concentration through titration experiments (1:500-1:2000)

  • Extend primary antibody incubation time (overnight at 4°C)

• Background reduction techniques:

  • Test alternative blocking agents (5% BSA, 5% non-fat milk, commercial blockers)

  • Increase washing stringency with higher salt concentrations or detergent

  • Use specialized low-background detection systems

  • Consider monovalent Fab fragments to reduce non-specific binding

Each optimization parameter should be systematically tested and documented to develop a reproducible protocol for your specific experimental system .

What approaches can resolve contradictory results between Western blotting and immunohistochemistry using BHLH23 Antibody?

Resolving contradictory results between techniques requires systematic troubleshooting:

  • Analyze buffer composition differences between techniques

• Technical validation strategy:

  • Perform epitope mapping to identify recognition sites

  • Test alternative antibody lots or sources

  • Use genetic controls (BHLH23 overexpression, CRISPR knockout lines)

  • Implement orthogonal detection methods (protein mass spectrometry)

• Interpretation framework:

  Factor	Western Blotting	Immunohistochemistry	Resolution Approach
  Protein denaturation	Complete denaturation	Native conformation	Test non-denaturing Western conditions
  Epitope accessibility	High	Variable	Use antigen retrieval methods
  Cross-reactivity risk	Molecular weight discrimination	Limited size discrimination	Pre-adsorb antibody with related proteins
