Mouse FITC, conjugated with Horseradish peroxidase Antibody

Horseradish peroxidase conjugated purified monoclonal mouse antibody to fluorescein isothiocyanate isomer 1. To enhance the specific signal obtained with a monoclonal antibody or a polyclonal second antibody conjugated to FITC. The phenomenon of a weak reaction of a monoclonal antibody is e.g. well known in different analysis of vital peripheral blood mononuclear cells in suspensions by the expression of surface markers. A similar situation exists in solid phase assay systems (ELISA, blotting, DIBA) when used for the identification and /or quantitative determination of minute amounts of soluble specific antigens or antibodies. The sensitivity of the FITC hapten-anti-hapten system makes it a valuable alternative to the biotin- avidin system. The optimum working dilution is an assay-related characteristic and should always be determined by titration. For histochemical use optimum dilutions are mostly from 1:100 to 1:500; in ELISA from 1:1,000 upwards; in Western blotting from 1:2,000 upwards. These data should be interpreted as general recommendations only.
