Description

Introduction to At3g58980 Antibody

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 .

Applications in Research

The At3g58980 Antibody enables targeted detection of its cognate protein in plant tissues. Key applications include:

  1. Western Blotting (WB):

    • Identifies the At3g58980 protein in Arabidopsis lysates.

    • Confirms protein expression levels under different experimental conditions (e.g., stress responses).

  2. ELISA:

    • Quantifies At3g58980 protein concentrations in plant extracts or recombinant preparations.

  3. Immunoprecipitation:

    • Isolates At3g58980 for downstream analysis of protein interactions (e.g., F-box protein complexes).

Limitations:

  • Limited data on cross-reactivity with homologous proteins in other species.

  • No reported use in immunohistochemistry (IHC) or immunofluorescence (IF) to date .

Challenges and Considerations in Antibody Use

While the At3g58980 Antibody is a valuable tool, researchers must address the following:

  1. Specificity Validation:

    • Confirm lack of cross-reactivity with non-target proteins via WB or immunoprecipitation .

    • Optimize blocking and washing conditions to minimize background noise.

  2. Quantitative Limitations:

    • ELISA results may require calibration using recombinant At3g58980 protein standards .

  3. Host-Specific Reactivity:

    • Limited to Arabidopsis thaliana; unsuitable for cross-species studies.

Future Directions and Research Opportunities

The At3g58980 Antibody could advance studies in:

  1. Protein Degradation Pathways:

    • Investigating At3g58980’s role in E3 ubiquitin ligase complexes, given its F-box domain .

  2. Stress Response Mechanisms:

    • Profiling At3g58980 expression under biotic or abiotic stress conditions.

  3. Antibody Optimization:

    • Developing monoclonal variants for higher specificity (e.g., as demonstrated for APOBEC3B antibodies ).
