• Careful temperature control during extraction (typically 4°C)

• Centrifugation parameters that separate cellular debris while retaining target proteins

• Protein quantification prior to antibody application to ensure consistent loading

The performance of the antibody may vary depending on whether samples are native, denatured, or fixed, with Western Blot applications typically requiring denatured proteins while some immunoassays may perform better with native conformations.

What controls should be included when working with CHX15 Antibody?

Rigorous experimental design with CHX15 Antibody requires multiple controls:

• Positive control: Use of known CHX15-expressing Arabidopsis thaliana samples or recombinant CHX15 protein

• Negative control: Samples from CHX15 knockout plants or tissues known not to express CHX15

• Antibody controls: Secondary antibody-only controls to assess non-specific binding

• Loading controls: Housekeeping proteins (e.g., actin, tubulin) for Western Blot normalization

• Blocking peptide control: Pre-incubation of antibody with synthetic CHX15 peptide to confirm specificity

These controls help distinguish specific signals from background and validate experimental findings, particularly important given the polyclonal nature of this antibody.

How can researchers optimize Western Blot protocols for CHX15 detection?

For optimal Western Blot detection of CHX15 in plant samples, researchers should consider:

• Sample preparation: Use SDS-based lysis buffers containing DTT or β-mercaptoethanol as reducing agents

• Gel percentage: 10-12% polyacrylamide gels typically provide good resolution for CHX15 detection

• Transfer conditions: Semi-dry transfer (15-20V for 30-45 minutes) or wet transfer (30V overnight at 4°C)

• Blocking: 5% non-fat dry milk or BSA in TBST for 1-2 hours at room temperature

• Primary antibody: Dilute CHX15 Antibody 1:1000 to 1:2000 in blocking solution; incubate overnight at 4°C

• Washing: 3-5 washes with TBST, 5-10 minutes each

• Secondary antibody: Anti-rabbit HRP-conjugated secondary antibody at 1:5000 to 1:10000 dilution

• Detection: Use enhanced chemiluminescence (ECL) substrate with exposure times optimized for signal intensity

Optimization may be required for specific research questions, including adjusting antibody concentrations and incubation times based on signal strength and background levels.
