CCN4/Wnt-induced secreted protein 1 (WISP1) is a secreted, cysteine-rich, heparin-binding glycoprotein, belonging to the CCN (CTGF/CYR61/NOV) family of growth factors, and is involved in diverse biological functions such as cell growth, adhesion, migration, angiogenesis, tissue repair, and regulation of extracellular matrix. Members of the CCN family demonstrate high structural homology sharing four conserved cysteine-rich modular domains: an IGFBP (insulin-like growth factor-binding) domain, a von Willebrand type C domain, a thrombospondin domain and a C-terminal cysteine -knot domain. WISP1 is a putative downstream effector of the Wnt/Frizzled pathway that mediates diverse developmental processes, was identified as an oncogene regulated by the Wnt-1-beta-catenin pathway. Thus WISP1 may contribute to Wnt-1-mediated tumorigenesis and malignance. Expression of WISP1 in some cells results in transformation and tumorigenesis. WISP1 acts to block cell death at a late stage in the p53-mediated apoptosis pathway. It was reported that WISP1 interacts with sulfated glycoconjugates, decorin and biglycan in the ECM of connective tissue, and possibly prevents their inhibitory activity in tumor cell proliferation.

Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
