Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.
Other clonesOverlap in epitope recognition with REA825
Cells were incubated with an excess of purified unconjugated p53 pS15 (REA825) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Specifications for p53 pS15 Antibody, anti-human, REAfinity™


Clone REA825 recognizes the human cellular tumor antigen p53 phosphorylated at serine 15 (pS15). The p53 protein is an important regulator of cell growth and, thus, functions as a tumor suppressor in many tumor types. The p53 tumor suppressor gene is altered or deleted in most solid human tumors. It is tightly regulated and plays a critical role in the cellular response to environmental stress. Upon a cell's exposure to stress, such as hypoxia or genomic damage, the p53 protein is expressed at high levels and is post-translationally modified. These modifications, which include phosphorylation, acetylation, and glycosylation, occur rapidly and lead to the activation of p53, resulting in either G1 growth arrest or programmed cell death. Following DNA damage, p53 is phosphorylated on serine residues 15, 20, 33, and 37 within the amino-terminal domain. These phosphorylation events are thought to play a key role in regulating p53 stability and activity.
Additional information: Clone REA825 displays negligible binding to Fc receptors.
