biovision K7408-100 ? Serum & plasma (heparin, EDTA) ? Cell culture supernatants ? Detection method- Absorbance (450 nm) ? Species reactivity-human ? Application- Quantitative protein detection, establishing normal range etc. Cathepsin B (human) ELISA Kit: Colorimetric Assay for Quantitative measurement of human Cathepsin B in serum, plasma & cell culture supernatants. Detection Range: 156 pg/ml - 10,000 pg/ml. 100 assays. BioVision’s human Cathepsin B ELISA Kit is based on the standard sandwich enzyme-linked immunosorbent assay technology. This assay employs a monoclonal antibody form mouse specific for Cathepsin B coated on a 96-well plate. Standards (NSO, R18-I339) and test samples are added to the wells and Cathepsin B present in a sample is bound to the wells by the immobilized antibody. A biotinylated detection polyclonal antibody from goat specific for Cathepsin B is added subsequently. After washing away the unbound biotinylated antibody with PBS or TBS buffer, Avidin-Biotin-Peroxidase Complex is added to the wells. The wells are again washed with PBS or TBS buffer to remove the unbound conjugates. HRP substrate TMB is 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 color is proportional to the human Cathepsin B captured onto the plate. This ELISA kit shows no cross-reactivity with other relevant proteins. Detection Range: 156 pg/ml – 10,000 pg/ml. Sensitivity: < 5 pg/ml.
