Understanding C3 (Complement 3) Reagent

The Complement system, which consists of a series of circulating blood proteins, serves as crucial mediators of the inflammatory response. C3, comprising approximately 70% of the total protein in the complement system, holds central importance in activating both the classical and alternate pathways. Consequently, measurements of this protein are invaluable in diagnosing immunologic disorders, particularly those associated with deficiencies of complement components.


In this methodology, immune complexes formed in solution scatter light based on their size, shape, and concentration. Utilizing turbidimeters, the reduction of incident light caused by reflection, absorption, or scatter is measured. Specifically, the measurement focuses on the decrease in light transmitted (increase in absorbance) through suspended particles resulting from complexes formed during the antigen-antibody reaction. This forms the basis of this assay, allowing for accurate analysis and diagnosis.
