General description

Complement C3 deficient serum is a normal human serum in which C3 protein is removed by affinity chromatography. Depleted serum helps in the complement cascade up to the preferred convertase level. It eases the formation of enzyme complex from purified components.

Application

Complement C3 deficient serum human has been used:
  • as a component of the culture medium to study the influence of the inhibition of complement activation on complement receptors (CR3 and C3aR) expression in CD3+CD56+NKT-like cells
  • as a negative control to evaluate the downstream complement activation post-mannan-binding lectin (MBL) pathway activation
  • to study the opsonization of foreign particles by complement system

Physical form

Supplied as a solution in phosphate buffered saline, pH 7.4

Analysis Note

C3 is depleted by immunoadsorption as judged by a highly sensitive hemolytic assay.

The complement system and the natural antibody repertoire provide a critical first-line defense against infection. The binding of natural antibodies to microbial surfaces opsonizes invading microorganisms and activates complement via the classical pathway. Both defense systems cooperate within the innate
