Concanavalin A (agarose) 由Concanavalin A 与琼脂糖偶联而成。Concanavalin A 是一种从刀豆 (Canavalia ensiformis) 中提取的四聚体金属蛋白凝集素。Concanavalin A (agarose) 能结合含有 α-D-吡喃甘露糖基、α-D-吡喃葡萄糖基及其空间相关残基的分子,用于纯化糖蛋白、多糖和糖脂。此外,Concanavalin A (agarose) 还用于酶抗体缀合物的纯化、IgM 的纯化与膜囊泡的分离等领域。
Benastatin C is a polyketide synthase-derived benastatin that has been found inStreptomycesand has diverse biological activities.1,2It inhibits glutathione S-transferase (GST; IC50= 24 μg ml for the rat liver enzyme).2Benastatin C also inhibits the esterase activity of isolated porcine pancreatic lipase (IC50= 10 μg ml). It increases LPS- or concanavalin A-induced blastogenesis of isolated mouse spleen lymphocytes in a concentration-dependent manner. 1.Xu, Z., Schenk, A., and Hertweck, C.Molecular analysis of the benastatin biosynthetic pathway and genetic engineering of altered fatty acid-polyketide hybridsJ.
