Anti-FITC (alle,Chem) aus Maus (Klon: NI 239) – Biotin

The reactivity of the antiserum is directed to the FITC molecule as tested in direct binding enzyme immunoassay, ELISA and immunoblotting. 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 1:50 to 1:200, in ELISA from 1:500 upwards, in Western blotting from 1:1,000 upwards. These data should be interpreted as general recommendations only.
