The complement system is a complex network of proteins that work in harmony to defend the body against infections, clear cellular debris, and modulate immune responses. Its roles extend beyond immunity, influencing processes such as tissue repair, homeostasis, and autoimmune responses. The Complement ELISA Assay Kits can be used for university research, pharmaceutical research, or clinical research. Each kit comes with specialized instructions regarding the incubation time required, dynamic range, sample type, as well as kit reagent contents. Most kits come with controls necessary for each assay and the specific procedure required for the completion of the test.
