Synonym
CCN2, NOV2, HCS24, IGFBP8, IBP-8, IGFBP-8, IGF-binding protein 8
Source
Human CTGF, His Tag (CTF-H52H5) is expressed from human 293 cells (HEK293). It contains AA Gln 27 - Ala 349 (Accession # Q5M8T4-1).
Predicted N-terminus: Gln 27
Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 37.4 kDa. The protein migrates as 36-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Potassium glutamate and Arginine, pH7.0 with trehalose as protectant.

Background
Connective Tissue Growth Factor (CTGF), also known as CCN2, is a member of the CCN (CCN1-6) family of modular matricellular proteins. Like other CCN proteins, mature human CTGF consists of IGF-binding protein domain, a vWF-C domain, a TSP-1 domain, and a cysteine knot heparin-binding domain. CTGF promotes proliferation and differentiation of chondrocytes. Mediates heparin- and divalent cation-dependent cell adhesion in many cell types including fibroblasts, myofibroblasts, endothelial and epithelial cells. Enhances fibroblast growth factor-induced DNA synthesis. Analysis of CCN2 function in vivo has focused primarily on its key role as a mediator of excess ECM synthesis in multiple fibrotic diseases.
