Our Anti-p53 (Ser392) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human and rat p53 (Ser392) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of rat brain nuclear fraction lysate showing specific immunolabeling of the ~53 kDa p53 phosphorylated at Ser392 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 minutes).

Product Details
p53 (Ser392)
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 Ser-392 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)
