  • Product overview

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

    A Cathepsin B specific rat 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 mouse Cathepsin B amount of sample captured in plate.

I was interested in detecting secreted cathepsin B in rat hippocampal tissue. Although the kit uses antibodies designed against mouse, mouse and rat cathepsin B share >90% homology. I was able to successfully detect cathepsin B in the supernatant from organotypic hippocampal slices (D.I.V. 10-14) cultured from Wistar rats (P7). The assay was sensitive, showing a positive signal when tested with 200uL of serum-free media, which was washed over the slice for 10 minutes prior to processing. The assay also showed low well-to-well variability when identical samples were run on multiple wells. Serum-free culture media showed little or no reactivity.

Thank you for contacting Abcam.

I do apologize for the delay in returning this information to you, especially as I image you have already found the results from the mistaken mixing ofthe biotinylation solution with sample buffer instead of a...
