Product Description
Zymosan is prepared (Pillemer, L. and Ecker, E.E., (1941)) from actively growing yeast (Saccharomyces cerevisiae).After removal of cellular contents the isolated cell walls remain.This is zymosan and it is primarily composed of the highly cross-linked polysaccharides alpha-D-mannan, beta-D-glucan, and other minor polysaccharide polymers.Fresh zymosan, and especially zymosan stored as a dried powder, must be activated to develop its full complement-activating activity (Minta, J., 1983).This is done by refluxing zymosan in saline at 100oC for two hours.This process has been performed for customers on the zymosan offered by CompTech and it is sold as a pre-activated suspension in saline.The product has been shown to be stable for four years if kept frozen.It is stable at 4oC for several months if not contaminated by microbial growth.

Complement Technology的GVB o是一种基本缓冲液,可用于制备用于补体测定的其他传统缓冲液。可以将Ca ++和Mg ++添加到GVB o中,以制成用于经典途径和凝集素途径测定的GVB ++。可以将MgEGTA添加到GVB o中以进行替代途径测定。EDTA可被添加到GVB Ò准备GVBE抑制补体活化。GVB ø也用于血清和其它测定组分的稀释在许多补体测定中特别是在旁路途径测定(摩根,BP(2000;多兹,AW和Sim,RB(1997))。
