Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.
金黄色葡萄球菌蛋白A(SPA)重组蛋白Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验金黄色葡萄球菌A蛋白(Staphylococcal Protein A、简称SPA)是细胞壁抗原的主要成分,几乎90%以上的菌株均含有这种成分,但不同的菌株含量差别十分悬殊。SPA占整个细胞壁蛋白成分的6.7%,通过胞壁肽聚糖以共价键与之结合。其它葡萄球菌如表皮葡萄球菌、腐生葡萄球菌不含SPA。 SPA 的理化性质 SPA是一种蛋白质,由亮、缬、脯、丙、苏、甘、丝
