Here, we summarize possible ways of interpreting individual bands that can be visualized on gelatin zymography based on their molecular weight. These interpretations have been reported in the papers cited below. Note that these interpretations need further confirmation with techniques such as Western blots or cutting out the bands and sending them off for sequencing by a proteomics center (let me know if you are aware of other ways to identify them by sending an email to firstname.lastname@example.org).
