| pubmed-article:1431148 | pubmed:abstractText | An enzyme immunoassay involving activation of complement (C-EIA) was developed for rabbit polyclonal IgM antibodies against lipid A and lipopolysaccharide antigens. C-EIA was significantly higher in sensitivity for IgM-rich rabbit sera compared to EIA using anti-immunoglobulin secondary antibodies. Hence, C-EIA should be useful for the detection of weak IgM reactivities in rabbit sera, especially after short-time immunizations. Selective inhibition of both complement pathways indicated that C-EIA measures activation of the classical pathway. | lld:pubmed |
