The At3g58980 Antibody is a rabbit polyclonal antibody designed to target the protein product of the At3g58980 gene in Arabidopsis thaliana (mouse-ear cress). This antibody is primarily used in plant molecular biology research to study the F-box/LRR-repeat protein encoded by the gene, which may play roles in protein degradation or regulatory pathways. The antibody is commercially available from suppliers like MyBioSource and Cusabio, with applications in Western blotting (WB), enzyme-linked immunosorbent assay (ELISA), and immunoprecipitation .
The At3g58980 Antibody enables targeted detection of its cognate protein in plant tissues. Key applications include:

Antibody Optimization:
Here’s a structured collection of FAQs tailored for researchers working with the At3g58980 Antibody in academic settings, integrating technical depth and methodological guidance:
Advanced Considerations:
Fixation: Use 4% paraformaldehyde for 2 hr to preserve epitopes without over-fixation.
Antigen retrieval: Optimize citrate buffer pH (6.0–6.5) and heating time (10–15 min) to balance signal intensity and tissue integrity.
Blocking: 5% BSA + 0.1% Tween-20 reduces non-specific binding in lignified plant tissues .
Analytical Framework:
Technical variables: Compare fixation methods, antibody dilutions, and imaging platforms used in conflicting studies.
Biological context: Assess growth conditions (e.g., stress treatments) that may alter protein expression patterns.
Orthogonal validation: Combine immunofluorescence with in situ hybridization or GFP-tagged transgenic lines .
Methodological Guidance:
Use linear mixed-effects models to account for batch effects in large-scale experiments.
Apply background subtraction algorithms (e.g., rolling-ball) to immunoblot data to minimize noise .
For longitudinal studies, employ ANOVA with repeated measures to track dynamic expression changes.
Advanced Strategy:
Generate dual gRNAs targeting exons 2 and 4 of At3g58980 to ensure frameshift mutations.
Include rescued lines (complemented with a cDNA transgene) to confirm phenotype causality.
Monitor off-target effects via RNA-seq in CRISPR lines vs. wild-type .
Integrated Workflow:
Predict conformational epitopes using AlphaFold2-predicted structures of P0C2G1.
Validate predictions via alanine-scanning mutagenesis coupled with ELISA .
Cross-reference with library-on-library binding data to identify critical residues .
Systematic Approach:
