Complement Proteins

General DescriptionSGVB⁺⁺ is a specialized buffer which is low in ionic strength (due to the low NaCl concentration), but isotonic (due to the sucrose). This combination of properties allows complement assays or binding assays to be performed with

General DescriptionVBS⁺⁺ is like the traditional buffer used in complement assays (GVB⁺⁺) but it lacks the carrier protein gelatin often used in these assays. GVB may be replaced with VBS if gelatin is undesirable or may interfere with the assays.

General DescriptionZymosan 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
