At1g25150 Antibody

What is AT1G25150 and why are antibodies against it valuable for research?

AT1G25150 encodes an F-box family protein in Arabidopsis thaliana that likely functions within SCF ubiquitin-ligase complexes involved in protein degradation pathways. Antibodies against this protein enable researchers to study its expression patterns, subcellular localization, and involvement in plant developmental processes. F-box proteins play crucial roles in protein turnover regulation, making antibodies against AT1G25150 important tools for investigating plant proteostasis mechanisms .

How do AT1G25150 antibodies complement transcriptomic data in expression studies?

While transcriptomic data provides information about mRNA expression, antibodies allow verification at the protein level. As demonstrated in antibody validation methods, protein and mRNA levels don't always correlate perfectly . Researchers in the Uhlén study showed that combining transcriptomic data with antibody-based protein detection provides more comprehensive validation of expression patterns, as protein levels can be affected by post-transcriptional regulation and protein stability factors .

What characteristics should researchers consider when selecting AT1G25150 antibodies?

When selecting antibodies, researchers should consider:

What are the recommended validation strategies for AT1G25150 antibodies?

Enhanced validation approaches described by Edfors et al. demonstrate the importance of multiple validation methods . For AT1G25150 antibodies, researchers should:

• Perform western blot analysis using wild-type plants alongside at1g25150 knockout lines

• Verify specificity through immunoprecipitation followed by mass spectrometry

• Conduct orthogonal validation comparing antibody detection with transcriptomic data

• Use genetic knockdown/overexpression systems to confirm signal specificity

The Edfors study showed that antibodies displaying Pearson correlation coefficients above 0.5 between orthogonal methods (antibody signal vs. transcriptomic data) are generally reliable .

How can researchers apply paired antibody validation approaches to AT1G25150?

Based on advanced validation methodologies, researchers should:

• Use multiple antibodies targeting different epitopes of AT1G25150

• Compare immunoblotting results with targeted mass spectrometry (PRM/SRM) data

• Correlate antibody signals with RNA expression levels across multiple tissues

• Document concordance between different detection methods

This multi-antibody approach helps resolve discrepancies, as demonstrated in the enhanced validation protocols where researchers found that some antibodies showing poor correlation with transcriptomic data were actually detecting modified protein forms rather than being non-specific .

What controls are essential when using AT1G25150 antibodies?

Essential controls include:

• Negative controls using at1g25150 knockout plants

• Peptide competition assays where antibody is pre-incubated with immunizing peptide

Multiple bands may represent:

• Differentially modified forms of AT1G25150

• Alternatively spliced isoforms
