Protocols

Specificity / Sensitivity

PPARγ (C26H12) Rabbit mAb detects endogenous levels of total PPARγ protein.

Source / Purification

PPARγ (C26H12) Rabbit mAb is produced by immunizing rabbits with a synthetic peptide corresponding to residues surrounding Asp69 of human PPARγ.

Background

Peroxisome proliferator-activated receptor γ (PPARγ) is a member of the ligand-activated nuclear receptor superfamily and functions as a transcriptional activator (1). PPARγ is preferentially expressed in adipocytes as well as in vascular smooth muscle cells and macrophage (2). Besides its role in mediating adipogenesis and lipid metabolism (2), PPARγ also modulates insulin sensitivity, cell proliferation and inflammation (3). PPARγ transcriptional activity is inhibited by MAP kinase phosphorylation of PPARγ at Ser84 (4,5).
