Complement Function Assay Services

The complement system plays an important role in chronic, autoimmune and infectious diseases. It contains a set of proteins that, when activated, cause the lysis of target cells and promote phagocytosis through opsonization. This plasma protein system can be directly activated by pathogens or indirectly by pathogen-bound antibodies, leading to a series of reactions involving more than 35 proteins that occur on the surface of pathogens and producing active ingredients with multiple effector functions.

There are three pathways for complement activation, namely the classic pathway, the alternative pathway and the recently discovered MB-lectin pathway. Creative Biolabs provides a complete solution for complement function analysis. Our supplement product portfolio includes active biomarkers and functional assessment of all three pathways. These assays are designed as flexible and easy-to-use enzyme immunoassays and off-the-shelf reagents, which provide a short incubation time, thereby shortening the user's hands-on time.

Complement Functional Testing for Non-Clinical & Clinical Trials

Complement Function Assay Services

With our extensive knowledge of complement function testing, our in-house laboratory services have been developed to comply with GLP, GCP and ISO 17025, ensuring compliance with regulatory requirements. A comprehensive menu of markers for complement function and activation is provided, as well as a test package for evaluating complement defects and complement function.

Creative Biolabs provides complement function assays for various applications in drug development and clinical research:

Complement Function Assay Services- Hemolytic or ELISA

Our complement function is determined by ELISA, which can be carried out on higher through-hole 96-well plates, and depends on the deposition of complement components on the activated surface of the plate. Our complement function/activity test includes:
