Product overview

Name SLIGRL-NH2
Biological description

Overview

SLIGRL-NH2 is a PAR2 peptide agonist which is specific for activation of PAR2 over PAR1 and PAR4 (EC50 = 0.5-2.0µM).

The peptide is derived from the N-terminus of the rat PAR2 receptor sequence.

Uses

SLIGRL-NH2 is an itch-inducing agent which is commonly used to study histamine-independent itch. It evokes dose dependent scratching behaviour in mice. Interestingly, in pruritogen-responsive neurons that transmit the itch signal induced by SLIGRL-NH2, sex-related differences may exist.

The peptide has also been shown to enhance gastrointestinal transit in mice and rats

Active in vivo.
