At2g14710 Antibody

What is the At2g14710 gene and what experimental approaches are recommended for antibody validation?

At2g14710 is an Arabidopsis thaliana gene located on chromosome 2. When working with antibodies targeting this protein, proper validation is essential for experimental reliability. For antibody validation, implement a multi-step approach:

• Direct binding assays should include both positive controls and at least one isotype-matched, irrelevant (negative) control antibody

• Include negative antigen controls with chemically similar but antigenically unrelated compounds

• Whenever possible, biochemically define the protein bearing the reactive epitope

• Conduct fine specificity studies using antigenic preparations of defined structure through inhibition techniques

• Quantitate antibody binding activity through affinity, avidity, and immunoreactivity assays

This systematic validation process ensures antibody specificity before proceeding with experimental applications.
