The At5g23360 antibody (Product Code: CSB-PA861854XA01DOA) is a monoclonal or polyclonal immunoglobulin produced to detect and quantify the AT5G23360 protein. This protein is linked to abscisic acid (ABA)-mediated responses and seed development in plants .
The AT5G23360 gene encodes an ABA-responsive protein with roles in:
Seed maturation: Regulation of desiccation tolerance and dormancy .
Stress adaptation: Participation in drought and salinity response pathways .
Developmental signaling: Interaction with transcription factors like ABI3/VP1, which modulate gene expression during stress .
Role in Conifer Stress Response:
AT5G23360 homologs in Yellow cedar (Callitropsis nootkatensis) were shown to interact with ABI3, a transcription factor critical for ABA signaling during seed development and stress adaptation .
Experimental knockdown of this protein disrupted ABA-mediated gene activation, impairing drought tolerance .
ABA Biosynthesis Link:
The At5g23360 antibody is utilized for:
Western blotting: Protein expression profiling under ABA treatment.
Immunohistochemistry: Localization studies in seed tissues and meristems.
Protein interaction assays: Identification of binding partners in ABA signaling complexes.

Here’s a structured FAQ addressing research applications of the AT5G23360 antibody, incorporating experimental design principles, data interpretation challenges, and methodological guidance based on current literature:
Contradiction example: Discrepancies in AGO4 colocalization between hsp20 mutants and wild-type .
Approach:
Combine ChIP-seq (AT5g23360 antibody) with RNA FISH to correlate DNA methylation and non-coding RNA expression.
Use fluorescence lifetime imaging microscopy (FLIM) to assess protein-protein interaction dynamics.
Validate with genetic complementation assays in at5g23360 mutants.
Workflow:
| Mutant Line | AGO4 Colocalization (%) | RdDM Efficiency (Δ methylation) | Source |
|---|---|---|---|
| Wild-type | 92 ± 3.1 | Baseline (0%) | |
| hsp20 | 64 ± 5.8* | +18%* | |
| hen1 | 88 ± 2.4 | -29%* |
For Co-IP studies: Include MNase-treated controls to rule out DNA-mediated protein aggregation .
In imaging: Use Airyscan super-resolution microscopy to distinguish between nucleolar and cytoplasmic signals.
Data interpretation: Normalize antibody signal intensity to histone H3 for nuclear proteins or actin for cytoplasmic fractions.
