Studying CYP72A14 is important for understanding plant adaptation mechanisms, metabolic pathways, and potential applications in agricultural biotechnology. Antibodies against CYP72A14 enable researchers to detect and quantify this protein in various experimental setups, facilitating studies on its expression patterns, localization, and functional roles in plant physiology .

What applications are validated for CYP72A14 antibody?

CYP72A14 antibody has been validated for several research applications, primarily ELISA (Enzyme-Linked Immunosorbent Assay) and Western Blot (WB) techniques for protein detection and quantification . When designing experiments, researchers should be aware that antibody performance can vary between applications. For optimal results, preliminary validation experiments should be conducted for each specific application, even if not explicitly listed in the product documentation. This may include titration experiments to determine optimal antibody concentration and validation of specificity using appropriate positive and negative controls.

How should CYP72A14 antibody be stored and handled to maintain reactivity?

For optimal performance and longevity, CYP72A14 antibody should be stored at -20°C or -80°C upon receipt. Repeated freeze-thaw cycles should be avoided as they can compromise antibody function. The antibody is typically supplied in a storage buffer containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative . For working solutions, aliquoting the stock antibody into smaller volumes before freezing is recommended to minimize freeze-thaw cycles. When handling the antibody, use clean pipette tips and sterile tubes to prevent contamination.

What controls should be included when using CYP72A14 antibody?

When designing experiments with CYP72A14 antibody, several controls should be included to ensure reliable and interpretable results:
