The At4g15060 Antibody is a research-grade monoclonal antibody targeting the protein encoded by the At4g15060 gene in Arabidopsis thaliana (mouse-ear cress), a model organism in plant biology. This antibody is commercially available through specialized biotechnology suppliers (e.g., Cusabio) and is utilized to study gene expression, protein localization, and functional roles of the At4g15060 protein in cellular processes .
The At4g15060 Antibody has been employed to analyze gene expression patterns in Arabidopsis. For example, in a study investigating histone demethylation in Arabidopsis, the antibody was used to detect downregulated expression of At4g15060 under specific experimental conditions:
| Experiment | Observation |
|---|---|
| Gene Expression | At4g15060 expression ↓ (p = 0.0541) |
| Antibody Dilution | 1:170 |
| Context | Linked to epigenetic regulation |
This suggests the antibody’s role in studying chromatin remodeling or stress responses in plants .
The At4g15060 gene encodes a protein potentially involved in F-box protein-related pathways, based on homology with known F-box proteins in Arabidopsis. These proteins often participate in ubiquitin-mediated protein degradation, a key regulatory mechanism in cellular processes .
While no peer-reviewed validation studies for this specific antibody are available in the provided sources, its use in Western blot and immunohistochemistry implies compatibility with standard protocols for plant protein detection. Commercial suppliers typically validate antibodies against recombinant proteins or knockout (KO) samples to ensure specificity .
Limited Public Data: Most information about the At4g15060 Antibody comes from commercial catalogs, with sparse experimental details in peer-reviewed literature.
Species-Specificity: The antibody is validated for Arabidopsis, limiting cross-reactivity claims with other plant species.
Dilution Optimization: While a 1:170 dilution was effective in one study, optimal conditions may vary by application (e.g., immunoprecipitation vs. IHC) .
Mechanistic Insights: The biological role of the At4g15060 protein remains poorly characterized.
Functional Studies: No data exist on the antibody’s utility in functional assays (e.g., protein interaction studies).
Perform Western blot with knockout mutants (e.g., T-DNA insertion lines) to confirm absence of signal in negative controls .
