The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 43 kDa (predicted molecular weight: 43 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use at an assay dependent concentration.
ELISA titre using peptide based assay: 1/62500.
FunctionCan efficiently cleave only ISG15 fusions including native ISG15 conjugates linked via isopeptide bonds. Necessary to maintain a critical cellular balance of ISG15-conjugated proteins in both healthy and stressed organisms.
Sequence similaritiesBelongs to the peptidase C19 family.
