Invitrogen™ Human PDEF (aa 92-158) Control Fragment Recombinant Protein

Descripción

Highest antigen sequence indentity to the following orthologs: Mouse (79%), Rat (79%). This recombinant protein control fragment may be used for blocking experiments. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

PDEF (prostate-derived Ets factor) is a 37.5-kDa protein that acts as an androgen-independent transcriptional activator for the PSA (prostate specific antigen) promoter. It also interacts directly with the DNA binding domain of androgen receptor and enhances androgen-mediated activation of the PSA promoter. PDEF was shown to have transcript levels 192-fold higher in the peripheral blood of some breast cancer patients in comparison with normal individuals. PDEF mRNA is also frequently over-expressed in human breast tumors as well as in human ovarian tumors. In ovarian tumors, PDEF expression seems to down-modulate malignant potential, and thus provides a rationale to screen for drugs that induce PDEF expression in epithelial ovarian tumors.
