Recombinant RFP (wild type, sequence corresponding to RFP, Discosoma spp.) is intended for use as a control when using polyclonal or monoclonal anti-RFP in immunological assays, in fluorometry, and in fluorescence activated cell sorting (FACS). Polyclonal anti-RFP can detect RFP by ELISA and western blot. Biotin conjugated polyclonal anti-RFP used in a sandwich ELISA is well suited to titrate RFP in solution when used in combination with unconjugated anti-RFP antibody. This product can be used as a control in western blots.Synonyms: DsRed, rDsRed, Discosoma sp. Red Fluorescent Protein, Red fluorescent protein drFP583
