PAMAM dendritic polymers can bind with antibody, combining with the conventional ELISA methods, it can be used for the in vitro detection of TAFI levels, opening up a new method of in vitro TAFI diagnostics to improve the detection sensitivity. TAFI levels in vitro test kit contains a monoclonal antibody specific for the TAFI and enzyme-linked immunoassay reagents required, and according to the biological characteristics of PAMAM with amino end groups, using PAMAM labeled antibody method for detecting human biological samples content of TAFI in vitro test, which solves the existing disadvantages of expensive device technology and long defect detection time. For clinical predictors of cardiovascular disease, making it simple, fast, low cost, diagnostic sensitivity, low detection limit. Weihai CY Dendrimer Technology Co.
