Recombinant Human CTLA4 Protein (36-161aa), C-hIgG-His-Tagged

Product Description

Cat

IMP-9509

Official Symbol

CTLA4

Product Overview

Recombinant human CTLA4, fused to hIgG His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.

Description

CTLA-4, also known as cytotoxic T-lymphocyte protein 4, is a type I transmembrane T cell inhibitory molecule that is a member of the Ig superfamily. The affinity of CTLA-4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28.
