The identifier "At5g35995" likely refers to a gene in Arabidopsis thaliana (Mouse-ear cress), a model organism commonly used in plant biology. Antibodies targeting Arabidopsis proteins are often custom-generated for research purposes, such as studying gene function, protein localization, or post-translational modifications . For example, Cusabio’s antibody catalog lists numerous Arabidopsis antibodies (e.g., At5g38670, At4g11750), but At5g35995 is absent from the provided data .
While specific data for At5g35995 Antibody is unavailable, antibodies targeting plant proteins typically share the following features:
Cross-reactivity risks: Antibodies may bind non-target proteins with similar epitopes. For example, the anti-glucocorticoid receptor (GR) antibody clone 5E4 was shown to target AMPD2 and TRIM28 instead of GR .
Validation strategies: Rigorous testing using methods like CRISPR knockdown, orthogonal assays, or competitive peptide adsorption is critical .
Custom antibody synthesis: Plant-specific antibodies are often generated via immunization with recombinant proteins or synthetic peptides .
Purification: Affinity chromatography (e.g., Protein A/G beads) or tag-based purification (e.g., V5-tag antibodies) ensures specificity .
(Note: This table is illustrative, as no real data exists for this antibody.)
Consult Specialized Databases:
The AbDb database (www.bioinf.org.uk/abs/abdb/) catalogs antibody structures but does not include plant-specific antibodies .
TAIR (The Arabidopsis Information Resource) may list antibodies for At5g35995.
Experimental Validation:
Collaboration with Antibody Vendors:
The Arabidopsis thaliana F-box/RNI-like superfamily protein (AT5G35995) is a plant-specific gene with limited directly available antibody research data. Based on analysis of protein homologs, antibody validation methodologies, and experimental design principles from related studies, here are structured FAQs for academic researchers:
Implement triple validation:
Antibody-based detection (Western blot)
Transcript analysis (RT-qPCR with primers spanning exon-exon junctions)
Promoter-GUS reporter lines
Common pitfalls and solutions:
Required experimental controls:
Lambda phosphatase-treated samples
Phos-tag™ SDS-PAGE with/without phosphatase inhibitors
Mass spectrometry validation of at least 20% phosphopeptide coverage
Test antibody against:
| Species | Protein Identity | Expected Reactivity |
|---|---|---|
| A. lyrata | 92% | Strong |
| Brassica napus | 78% | Weak |
| Oryza sativa | 65% | None |
Use quantitative ELISA with recombinant proteins for cross-reactivity thresholds .
Critical parameters:
Fixation: Vacuum infiltrate seedlings with 1% formaldehyde for 8 min
Sonication: 15 cycles (30 sec ON/30 sec OFF) at 4°C
