Streptavidin,Texas Redâ€šÃ Ã¶âˆšÃº labeled, is a highly fluorescent conjugate of streptavidin. This red fluorescent product excites at about 595 nm and has the light emission maximum at around 615 nm. Since the excitation and emission maxima are well separated from those of fluorescein,Texas Redâ€šÃ Ã¶âˆšÃº Streptavidin can be employed with Fluorescein Streptavidin or other fluorescein conjugates to simultaneously localize multiple antigens in the same tissue section. bioWORLDâ€šÃ Ã¶â€šÃ¢â€ s fluorochrome-conjugated streptavidin is prepared using recombinant protein and highly pure dye that exhibit very low non-specific binding. OurTexas Redâ€šÃ Ã¶âˆšÃº Streptavidin retains high affinity forBiotin and can be used to detectBiotinylated secondary antibodies and other macromolecules in a variety of applications such as immunofluorescence, flow cytometry, or in situ hybridization. This reagent can be used for amplification of fluorescent signals withBiotinylated secondary antibodies followed by another layer of highly purified fluorochrome-labeled streptavidin or avidin.
