Human Complement C3 (C3) ELISA Kit

A Sandwich ELISA kit from Assay Genie enables quantitative measurement of human Complement C3 in serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids. Complement C3 plays a central role in the complement system, supporting immune defense and inflammation regulation, with dysregulation associated with autoimmune disorders, infections, and inflammatory conditions.

The kit offers a sensitivity of 3.9 ng/mL across a detection range of 7.8-500 ng/mL. Reported intra-assay precision is 6.1% CV and inter-assay precision is 9.2% CV. Recovery averages 96% for serum (range 90-102%) and 98% for plasma (range 92-104%), with linearity characterised across serial dilutions of serum, EDTA plasma, and heparin plasma samples.

Colorimetric readout is measured at 450 nm following substrate development. The kit is for research use only and supports immunology research applications.
