P53 (TP53) (pSer392) antibody

Antigen: P53 (TP53)

Epitope: pSer392

Clonality: Polyclonal

Host: Rabbit

Reactivity: Rat (Rattus)

Application: Western Blotting (WB)

Catalog no.: ABIN361513

Additional Information

Alternative name: Phospho-Ser392 p53

Format: Affinity-purified

Description: 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). Anti-Phospho Ser392 p53 Western blot of rat brain nuclear fraction lysate showing specific immunolabeling of the ~53k p53 phosphorylated at Ser392 (Control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase: (-Ptase). The blot is identical to the control except that it was incubated in (-Ptase (1200 units for 30 min) before being exposed to the phospho Ser392 p53 antibody. The immunolabeling is completely eliminated by treatment with (-Ptase.

Specificity: Specific for the ~53k p53 protein phosphorylated at Ser392. The immunolabeling is completely eliminated by (-phosphatase treatment.

Application Details

Application Notes: Recommended Dilution: WB: 1:1000 Quality Control: Western blots performed on each lot.

Purification: Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.

Storage: Store at -20 °C, stable for 1 year

Restrictions: For Research Use only
