General description

The complement serum standard human is suitable for the determination of CH50 and AP50 complement activities. This allows for a test of the complement activity on the capacity of the serum to lyse red blood cells in vitro and can be used in procedures for genotyping DNA samples of the complement system.

Application

Complement Serum Standard human has been used as a positive control to study the role of the complement system in immunological demyelination of the spinal cord from mammals.[1]

Biochem/physiol Actions

The complement system is an important constituent of innate immunity.[2] It participates in the first line of defense against microbial infections, altered host cells, and removal of immune complexes and injured cells. The complement system comprises more than thirty components such as the plasma proteins produced by the liver, membrane proteins expressed on the cell surface, cytokines, and hormones.[2][3] The complement proteins come together to opsonize the pathogens and initiate a cascade of inflammatory responses serving the immune cells to fight the infection and maintain homeostasis.[2]

Physical form

Supplied as a 0.22 μm filtered solution containing ~ 18 mM citrate, ~22 mM dextrose, ~3 mM phosphate and ~13 mM calcium
