Description :Rabbit Polyclonal Antibody

Species :Rabbit

Tag :

Expression System:

Sequence :

Specificity :Recognizes the p53 protein phosphorylated at serine 392

Cited Applications :WB

Cross Reactivity :Human and Rat

Host :Rabbit, IgG

Immunogen :Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser392 conjugated to KLH

Purification :Affinity Chromatography

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

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

Scientific Background :p53 is a key regulator of cell growth and acts as a tumor suppressor gene. Wild-type p53 gene can suppress transformation of rat embryo fibroblasts in cell culture by other oncogenes such as the adenovirus E1A and Ras (1). DNA tumor viruses such as SV40 large T antigen and the adenovirus E1A plus E1B-55Kd proteins bind to p53 and inactivate its tumor suppressor activities leading to cellular transformation. Mutational inactivation of the p53 gene is detected in more than 50% of human cancers. Mutation of p53 renders cancer cells more resistant to current cancer therapies due to lack of p53-mediated apoptosis (2).
