  • Product overview

    Abcam’s Human Cathepsin B in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Human Cathepsin B in cell culture supernatants, serum and plasma (heparin, EDTA).

    A Cathepsin B specific mouse monoclonal antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells and incubated. A biotinylated detection polyclonal antibody from goat, specific for Cathepsin B is then added followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. TMB is then used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the Human Cathepsin B amount of sample captured in plate.

Sandwich ELISA Use at an assay dependent concentration.


  • Cathepsin B measured in culture supernatants from control (-) or stimulated cells cells (P/L: 24 hours with 50 ng x mL-1 of PMA (ab120297) with 1 ug x mL-1 of LPS (Sigma) for the last 6 hours; PHA: 48 hours with 2% PHA-M; LifeTechnologies). Data shown represents duplicates (+/- SD), samples tested in the dilution range of 1/1-1/20.

  • Cathepsin B measured in biological fluids (tested in the range of 1/10-1/1000; duplicates +/- SD).

  • Representative Standard Curve Using ab119584.

J’ai eu une réponse du laboratoire qui m’a confirmé que les plaques sont divisibles. La plaque peut être divisé en 12 donc vous pouvez tester 8 échantillons à chaque fois.

Une fois ouvert, le kit doit être stocké à 4ºC et la plaque doit être gardé bien au sec. Nous garantissons ce kit pour 6 mois après la date de livraison.

Thank you for contacting us and sorry for the delay in getting back to you.

I can confirm that the Cathepsin B Human ELISA Kit (ab119584) can detect both the mature form and uncleaved form of Cathepasin B.

The kit has been found to work well with cell culture supernatant, serum, plasma as well as tissue extracts.
