| Background | Phosphoinositide 3-kinase (PI3K) catalyzes the production of phosphatidylinositol-3,4,5-triphosphate by phosphorylating phosphatidylinositol (PI), phosphatidylinositol-4-phosphate (PIP), and phosphatidylinositol-4,5-bisphosphate (PIP2). Growth factors and hormones trigger this phosphorylation event, which in turn coordinates cell growth, cell cycle entry, cell migration, and cell survival. PTEN reverses this process, and research studies have shown that the PI3K signaling pathway is constitutively activated in human cancers that have loss of function of PTEN. PI3Ks are composed of a catalytic subunit (p110) and a regulatory subunit. Various isoforms of the catalytic subunit (p110α, p110β, p110γ, and p110δ) have been isolated, and the regulatory subunits are p85α, p85β and p55γ. p85α (PIK3R1) is one of the regulatory subunits that associated with the class IA PI 3-Kinases. Composed of one SH3 and two SH2 domains, p85 alpha functions as an adaptor, coupling catalytic p110 to activated receptor tyrosine kinases. Phosphoinositide 3-kinase p85β subunit (PI3-Kinase p85 beta ), also called regulatory subunit 2 (PIK3-R2) is an 85 kDa, 728 amino acid (aa) regulatory subunit of the PI3K complex. It shares ubiquitous expression and overlapping function with the p85 alpha subunit, but the two are differentially phosphorylated and may have different effects on apoptosis. Within aa 516-642, human p85 beta shares 97%, 96% and 68% aa identity with mouse and rat p85 beta and human p85 alpha, respectively. Full-length human p85 alpha and p85 beta share 59% aa identity. p55γ (Protein of 55 kDa, gamma subunit; also PI3-kinase regulatory subunit gamma and p55PIK) is a 55-57 kDa member of the PI3K p85 family of regulatory subunits. It is widely expressed, and serves as a recruitment subunit for the p110 catalytic subunit of PI3 kinase. p55 gamma /p55PIK should not be confused with the 55 kDa alpha splice variant of the p85a gene (75% amino acid [aa] identity). Human p55 gamma is 461 aa in length. It contains a unique 34 aa N-terminus that binds Rb and prevents cycle progression, followed by a Pro-rich region (aa 35-44) and two SH2 domains that bind the p110 catalytic subunit (aa 65-160 and 358-452). Based on mouse, it is likely that alternate start sites at Met8 and Met32 generate 54 and 50 kDa protein products, respectively. There is also a potential for a start site 18 aa upstream of the standard start site, as well as a splice form that shows a deletion of aa 256-314 that may be accompanied by an additional deletion of aa 36-71. Over aa 251-378, human p55 gamma shares 94% aa identity with mouse p55 gamma. |

保存条件：
PI3 Kinase p85α Rabbit Polyclonal Antibody -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。
