Abstract
Native and recombinant collectins are purified by using mannan-agarose and an anti-collectin antibody column. The use of sandwich enzyme-linked immunosorbent assay (ELISA) with two antibodies against human mannan-binding lectin (MBL) enables elucidation of the collectin concentration in the blood, serum, and plasma. The collectin sugar specificity is demonstrated by determining the concentration of saccharide required to inhibit sugar binding by 50% in a saccharide-binding assay. Biological analyses including the complement-dependent hemolysis test and several other methods are used to evaluate collectin.
