Description
Principle: This human EPCAM ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for EPCAM has been precoated onto 96-well plates. Standards(NSO, Q24 - K265) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for EPCAM is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human EPCAM amount of sample captured in plate.
Description: The Fast version of Picokine ELISA kits, assay takes less than 1.5 hours. Detect Human Trop1/EPCAM with <10pg/ml sensitivity. Format: 96-well plate with removable strips. Compatible samples: cell culture supernates, cell lysates, serum and plasma (heparin, EDTA). This is a TMB colorimetric sandwich ELISA kit with short assay time and fast experiment set up. Trop1/EPCAM tissue specificity: Highly and selectively expressed by undifferentiated rather than differentiated embryonic stem cells (ESC). Levels rapidly diminish as soon as ESC's differentiate (at protein levels). Expressed in almost all epithelial cell membranes but not on mesodermal or neural cell membranes. Found on the surface of adenocarcinoma.
