Background
|
Integrin alpha 2 (ITGA2 or CD49b) is one of twelve integrin family alpha subunits that share the beta 1 subunit. Integrin alpha 2 beta 1 is the non-covalent heterodimer of 160 kDa alpha 2 (CD49b) and 130 kDa beta 1 (CD29) type I transmembrane glycoprotein subunits and is one of six very late antigens on activated T cells, designated VLA2. The alpha 2 extracellular domain (ECD) contains an I (inserted) domain which includes the ligand binding site. The beta 1 ECD contains a vWFA domain, which participates in binding. Each subunit then has a transmembrane sequence and a short cytoplasmic tail. The dimer is folded when it is least active. Divalent cations and intracellular (inside-out) signaling convert it to its most active, extended and open conformation. The 1102 amino acid (aa) human alpha 2 extracellular domain (ECD) shares 83 89% aa sequence identity with mouse, rat, canine, bovine and equine alpha 2. The I domain-containing beta 1 integrins ( alpha 1 beta 1, alpha 2 beta 1, alpha 10 beta 1 and alpha 11 beta 1) all bind collagens, with alpha 2 beta 1 preferring collagens I III. Platelet alpha 2 beta 1, also called GPIa, cooperates with another adhesion protein, GPVI, to coordinate platelet collagen binding and activation. Other alpha 2 beta 1 ligands include laminin, decorin, E-cadherin, and collagen-like regions of collectin molecules such as C1q. Adhesion is synergized by crosstalk with syndecan-1 or HGF R/c-Met, and antagonized by crosstalk with Integrin alpha 1 beta 1. In addition to expression on selected hematopoietic cells, alpha 2 beta 1 is present on a wide variety of non-hematopoietic cells. Mice deficient in the alpha 2 subunit have defects in innate immune responses, wound mast cell infiltration and angiogenesis, and platelet responses to collagen. In innate immunity, alpha 2 beta 1 binding to C1q initiates the complement cascade and costimulates mast cell activation, triggering neutrophil influx.

保存条件：
ITGA2/CD49b 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。
