Summary for Patent: 5,869,277
Title: Method for measuring type IV collagenase
Abstract:The present invention relates to the development of a modified substrate capture immunoassay useful in the detection of a neutral metalloproteinase enzyme, type IV collagenase. Capture and immobilization of this enzyme can be achieved by coating the microtiter plate with gelatin, an alternative substrate for this enzyme. The captured enzyme can then be detected by affinity purified rabbit anti-type IV collagenase antibodies prepared against synthetic peptides from the amino terminus of the enzyme. Soluble type IV collagenase can readily be detected in samples known to contain this enzyme. Using purified enzyme this assay method can detect less than 50 ng of latent type IV collagenase. Using EDTA, an inhibitor of this metalloproteinase, gelatin binding can be shown to be independent of catalytic activity.
