clec-160 Antibody

Basic Research Questions

• What experimental systems validate clec-160 antibody specificity in C. elegans?

  • Perform western blotting against recombinant Hc-CLEC-160 protein (produced via pET-28a(+) vector in E. coli BL21) and native lysates from RNAi-treated worms .

  • Use immunofluorescence on paraffin sections of adult H. contortus (fixation: 4% paraformaldehyde; antigen retrieval with citrate buffer pH 6.0) .

  • Compare signal intensity in wild-type vs. clec-160(RNAi) mutants to confirm target specificity .

• How to design a qPCR workflow using clec-160 antibody for protein-mRNA correlation studies?

  • Pair antibody-based protein quantification with primers (e.g., Hc-clec-160 QF/QR; annealing temp: 60°C) for SYBR Green assays .

  • Normalize mRNA levels to β-tubulin (parasites) or actin-1 (model organisms) .

  • Address discordance between mRNA peaks (e.g., male adult worms) and undetectable protein via post-transcriptional regulation assays (e.g., cycloheximide chase) .

Advanced Research Challenges

• How to resolve contradictory data between clec-160 mRNA abundance and undetectable protein in immunoassays?

  • Hypothesis 1: Epitope inaccessibility due to protein glycosylation. Test with deglycosylation enzymes (e.g., PNGase F) .

  • Hypothesis 2: Transient expression windows. Conduct time-course IF staining across larval stages (L1–L4) .

  • Technical fix: Switch to epitope-tagged strains (e.g., GFP::clec-160) for orthogonal validation .

• What controls are critical for RNAi experiments using clec-160 antibody in cross-species studies?

  • Include species-specific antibody validation (e.g., C. elegans vs. H. contortus) .

  • Monitor off-target effects via RNA-seq of clec-160(RNAi) vs. empty vector controls .

  • Quantify phenotypic consistency: body length (↓13–18% in RNAi), brood size (↓22–30%) .

Methodological Optimization

• How to adapt clec-160 antibody protocols for non-model nematodes?

  • Pre-treat samples with collagenase (1 mg/ml, 37°C, 1 hr) to improve antibody penetration in cuticle-rich parasites .

  • Optimize fixation: Compare methanol (−20°C, 10 min) vs. paraformaldehyde for epitope preservation .

Ethical & Technical Considerations

• Antibody sourcing: Use commercial clec-160 antibodies (e.g., CSB-PA330347XA01CXY) with ≥1:10,000 ELISA titer for reproducibility .

• Conflict mitigation: Disclose batch variability by citing lot numbers in methods sections .
