Anti-p53 Antibody [H21-E] - Identical to Abcam (ab139565)

The H21-E rabbit monoclonal antibody from Antibodies.com is conjugated to fluorescein isothiocyanate (FITC) and validated for flow cytometry detection of human p53. Supplied as a liquid reagent sized for 100 tests, the antibody carries an IgG isotype and supports intracellular staining of the TP53 tumor suppressor in cell culture samples for research use only applications.

The FITC label allows excitation with a standard 488 nm blue laser and emission capture in the green channel, simplifying multicolor panel design. Researchers commonly apply this reagent to study DNA damage response, apoptosis, and oncogenic signaling pathways in human cell lines. The product should be refrigerated and protected from light to preserve fluorophore integrity, and aliquoted to limit freeze-thaw cycles.
