F. Legris et al., AN ULTRASENSITIVE CHEMILUMINOENZYME IMMUNOASSAY FOR THE QUANTIFICATION OF HUMAN TISSUE KININOGENS - APPLICATION TO SYNOVIAL-MEMBRANE AND CARTILAGE, Journal of immunological methods, 168(1), 1994, pp. 111-121
A sandwich enzyme immunoassay using a chemiluminescent detection has b
een developed for the quantification of total human (high and low mole
cular weight) kininogens in tissue extracts. This assay uses monospeci
fic polyclonal IgG labelled with alkaline phosphatase and the commerci
ally available dioxetane derivatives as substrates, for the detection
of immune complexes. This method exhibits a sensitivity level of 1 fmo
l/ml and allows a precise quantification of total kininogens in synovi
um and cartilage extracts. When characterized by Western blot, the imm
unoreactive material reveals the presence of both high and low molecul
ar weight kininogens.
