To enhance the specific signal obtained with a monoclonal antibody or a polyclonal second antibody conjugated to TRITC. 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 TRITC 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 1:10 to 1:40, in ELISA from 1:100 upwards, in Western blotting from 1:200 upwards. These data should be interpreted as general recommendations only.

Format
Lyophilized
Concentration
IgG concentration is 0.4 mg/ml. No foreign proteins added.
Buffer
Purified mouse IgG1 kappa lyophilized from a solution in phosphate buffered saline (pH 7.2).
Stock
4 °C/-20 °C
Stockage commentaire
The lyophilized product is shipped at ambient temperature and may be stored at +4 °C, prolonged storage at or below - 20 °C. Reconstitute the lyophilized ascites by adding 0.5 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Avoid repeated thawing and freezing. If a slight precipitation occurs upon storage, this should be removed by centrifugation and will not affect the performance of the product. Diluted solutions should be stored at +4 °C, not refrozen, and preferably used the same day.
