R&D Systems社組換え体タンパク質製品では通常ウシ血清アルブミン(BSA)をキャリアタンパク質として加えています。キャリアタンパク質を加えることで組換え体タンパク質の安定性が高まり、使用期限が長くなります。また、より濃度の低い溶液での保管も可能となります。CF製品はBSAが含まれない製品となります。一般的に細胞培養や、ELISAのスタンダードにはBSA含有製品を推奨しています。CF製品はBSAが影響してしまうアプリケーションに推奨されます。

Connective Tissue Growth Factor (CTGF), also known as CCN2, is a 36-38 kDa member of the CCN (CYR61/CTGF/NOV) family of secreted matricellular proteins (1). 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 (2). Human CTGF shares 94% amino acid (aa) sequence identity with mouse and rat CTGF. Alternative splicing generates an additional isoform with a 27 aa deletion within the TSP-1 domain. CTGF promotes cell adhesion through interactions with a range of cell surface molecules including heparan sulfate proteoglycans (HSPG), LRPAP, and Integrins  alpha M, alpha V beta 3, alpha 6 beta 1, alpha IIb beta 3 (3-7). It also binds to and regulates signaling through the Wnt receptors LRP6 and Frizzled-8 and the NGF receptors TrkA and NGF R (8, 9). In addition, CTGF binds directly to BMP-4, TGF-beta 1, TGF-beta 2, and VEGF 165 (10, 11). It blocks BMP-4 and VEGF induced responses but enhances TGF-beta induced responses (10-13). Within VEGF complexes, CTGF can be degraded by a variety of proteases, resulting in restoration of angiogenic activity (11). CTGF promotes fibroblast differentiation from mesenchymal stem cells and their production of type I Collagen and Tenascin C (5, 14). It promotes chondrocyte proliferation and cartilage matrix synthesis (15-17). CTGF is expressed in vascular mural and endothelial cells (EC) during development and promotes pericyte-EC association and angiogenesis (2, 17, 18, 19). It is expressed in the cerebral cortex and olfactory bulb and plays an important role in nervous system development (8, 12).
