Descriptions

Analysis Note

The sensitivity is <50 pg/mL for total p53, which is 8x more sensitive than immunoblotting.

Application

Designed for the in vitro quantitative determination of human p53 protein in cell lysates. The assay does not react with p53 in mouse and rat.

General description

A solid phase sandwich enzyme-linked immunosorbent assay (ELISA).

Application

p53 ELISA is designed to detect and quantify the levels of human p53 protein, independent of its phosphorylation state. It is used to provide the total p53 levels in the samples, which are simultaneously tested for p53 phosphorylated at serine 15.

Biochem/physiol Actions

p53 gene is highly conserved and expressed in normal tissues. It is the most commonly mutated gene in human cancer and more then 500 gene mutations have been described in various types of malignancies, hematologic as well as solid tumors. Intact p53 function is essential for the maintenance of the non-tumorogenic phenotype of cells. Thus, p53 plays a vital role in suppressing the development of cancer.

Features and Benefits

p53 ELISAs offer a fast (total assay time 4 hours), sensitive (<50 pg/mL for total p53 and <0.9 units/mL for phosphospecific p53, which is 8x more sensitive than immunoblotting), and an easy alternative to immunoblotting or other bioassays.
