Cathepsin B is a cysteine protease commonly overexpressed in metastisizing cancer cells. An intracellular (lysosomal) enzyme in peptidase family C1 (papain family), Cathepsin B will hydrolyze proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides. Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20C. Aliquots are stable at -20C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
