PEP-271 is a 14 amino acid synthetic peptide whose sequence corresponds to residues 113-126 of rat LXR beta. The sequence of this peptide is (amino to carboxy terminus): R113-Y-A-C-R-G-S-G-T-C-Q-M-D-A126
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product, LXR beta, catalog # PA1-333. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~70-fold) for competitive inhibition of antibody-protein binding reactions.
Reconstitute with 0.1 mL of distilled water.
The liver X receptors, LXRA and LXRB, form a subfamily of the nuclear receptor superfamily and are key regulators of macrophage function, controlling transcriptional programs involved in lipid homeostasis and inflammation. The inducible LXRA is highly expressed in liver, adrenal gland, intestine, adipose tissue, macrophages, lung, and kidney, whereas LXRB is ubiquitously expressed. Ligand-activated LXRs form obligate heterodimers with retinoid X receptors and regulate expression of target genes containing LXR response elements.
