|Calculated MW||53 KDa|
|Other Names||Cellular tumor antigen p53, Antigen NY-CO-13, Phosphoprotein p53, Tumor suppressor p53, TP53, P53|
|Target/Specificity||Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser392 conjugated to KLH.|
|Format||Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.|
|Antibody Specificity||Specific for the ~53k p53 protein phosphorylated at Ser392. The immunolabeling is completely eliminated by λ-phosphatase treatment.|

p53 has a well established role in blocking the proliferative action of damaged cells and acting in essence as an anticancer agent (Sharpless and DePinho, 2002; Yin et al., 1992). It has been called the guardian of the genome (Lane, 1992). Phosphorylation of Ser392 in p53 is associated with formation of human tumors (Saito et al., 2003; Pise-Masison et al., 1998; Kim et al., 2004). In addition, p53 has been linked to effects of aging and oxidative stress (Sharpless and DePinho, 2002). An increase in p53 has also been linked to deficits in LTP and learning and memory (Jiang et al., 1998).
