Purification and identification of 91-kDa neutrophil gelatinase. Release by the activating peptide interleukin-8.


Human neutrophils were found to release a 91-kDa gelatinase that is serologically related to tumor-derived gelatinolytic enzymes, as evidenced by immunoprecipitation. In order to identify the neutrophil gelatinase, the activity in conditioned medium from human neutrophil suspensions was purified by affinity chromatography on a gelatin substrate. The 91-kDa… (More)
