Additional Info


    Vector Laboratories fluorochrome-conjugated streptavidin and avidin reagents are highly purified and possess very low non-specific binding properties. They have extremely high affinity for biotin. These fluorescent conjugates can be used to detect biotinylated secondary antibodies and other macromolecules in applications such as immunofluorescence, in situ hybridization, or flow cytometry.

    Amplification of fluorescent signals can be easily achieved with our biotinylated secondary antibodies followed by our highly purified fluorochrome-labeled streptavidin or avidin. Using a biotin/avidin or biotin/streptavidin detection system results in an additional layer of amplification over a directly conjugated secondary antibody.

    Streptavidin, Texas Red® labeled, is a highly fluorescent conjugate of streptavidin and sulforhodamine 101. This red fluorescent product excites at about 595 nm and has an emission maximum at about 615 nm. Since the excitation and emission maxima are well separated from those of fluorescein, Texas Red® Streptavidin can be employed with Fluorescein Streptavidin or other fluorescein conjugates to simultaneously localize two antigens in the same tissue section. Texas Red® Streptavidin is also ideal for flow cytometry using instruments equipped with dye lasers.
