Citrate blood was taken from 18 healthy volunteers by brachial vein puncture and anti-adenoviral antibody titers were determined by ELISA, complement fixation test (CBR) and neutralizing assay.

It was called ‘complement’ because it aided the antibacterial activity of antibodies. However, it is now known that the complement system can be activated early in an infection without the presence of ...

In a recent study posted to the bioRxiv* pre-print server, researchers investigated the complement component 1q (C1q) binding and subsequent complement activation by neutralizing antibodies (nAbs) ...

New data link a common C3 gene variant to higher risk of chronic lung allograft dysfunction and antibody mediated rejection ...

The classical complement pathway typically requires antigen—antibody complexes (immune complexes) for activation (specific immune response), whereas the alternative pathway can be activated by C3 ...
