Background
The chondroitin sulfate proteoglycan CSPG4 (chondroitin sulfate proteoglycan 4), also named as NG2, is a type I membrane protein expressed by subpopulations of glia including oligodendroglial precursor cells and a variety of tumor cells. Normal precursor cells and malignant tumor cells migrate and proliferate, but there is evidence that cells may not be able to engage in both activities at the same time. However, NG2 is involved in promoting both proliferation and motility. The extracellular domain of NG2 sequesters growth factors and binds to both growth factor receptors and extracellular matrix ligands such as fibronectin, collagens and laminin. The cytoplasmic domain is involved in activating Rac, Cdc42 and p130 Cas. PKCα phosphorylates NG2 at Thr2256, triggering the redistribution of NG2 from apical microprocesses to lamellipodia accompanied by enhanced cell motility. ERK phosphorylates NG2 at Thr2314, stimulating cell proliferation. NG2, also known as CSPG4, MCSP, and AN2, is a 400-500 kDa transmembrane chondroitin sulfate proteoglycan (CSPG) with a protein core of approximately 300 kDa. The extracellular region can be proteolytically shed from the cell surface. Mature human NG2 consists of a 2195 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 77 aa cytoplasmic domain. Within aa 1583-2224, human NG2/CSPG4 shares 83% aa sequence identity with mouse and rat CSPG4. NG2 binds to the extracellular matrix proteins Laminin, Tenascin, and Collagens II, V, and VI as well as to the growth factors FGF-2 and PDGF-AA. NG2 is expressed on glial cell progenitors known as O2A cells or NG2 glia. These cells are neuronally responsive and differentiate primarily into oligodendrocytes but also into astrocytes. NG2 associates with PDGF R alpha and the AMPA R subunit GluR2. It is up-regulated on microglial cells during inflammation and contributes to the induction of inflammatory mediators. Various CSPGs in the brain inhibit neurite outgrowth through interactions with Nogo Receptor/NgR1 and NgR3. This recombinant protein product corresponds to the last 5 CSPG repeats, a region which can independently inhibit neurite outgrowth. NG2 is also expressed on vascular mural cells and capillaries. It promotes vascular endothelial cell (EC) migration and angiogenesis through interactions with Galectin-3 and Integrin alpha 3 beta 1 on EC, Plasminogen, and Angiostatin. NG2 is also expressed on a variety of tumors where it contributes to tumor cell adhesion, motility, and invasion.

保存条件：
CSPG4/NG2/MCSP Rabbit Polyclonal Antibody (KO Validated) -20ºC保存，Western一抗稀释液-20ºC或4ºC保存，一年有效。Western一抗稀释液优先推荐4ºC保存，长期不使用可以考虑-20ºC保存，但冻融可能会导致出现轻微的浑浊和少量不溶物。
注意事项：
如果本抗体用于Western blot (WB)、免疫荧光(IF)、免疫细胞化学(ICC)等实验，请注意回收使用过的稀释抗体。回收的抗体通常至少可以重复使用5-10次。稀释后的抗体，包括已经使用过的稀释抗体，请4℃保存。
回收后重复使用的抗体，使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象，可以10,000g离心1-3分钟，取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况，则可以考虑废弃该抗体。
提供的Western一抗稀释液也可以用于免疫荧光(IF)、免疫组化(IHC)、免疫细胞化学(ICC)等适当用途。如果希望获得最佳的检测效果，请考虑使用上述检测专用的一抗稀释液。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。
