Streptavidin-iFluor 750(R)-xtra conjugate

Streptavidin-iFluor(R) 750(R)-xtra Conjugate is a highly sensitive fluorescent reagent designed for detecting biotinylated biomolecules with near-infrared fluorescence. It features a streptavidin core for strong, specific binding to biotin, and is conjugated to iFluor(R) 750, a photostable fluorophore with excitation/emission maxima around 755/778 nm. The near-infrared emission of iFluor(R) 750-xtra minimizes background autofluorescence interference and avoids spectral overlap with visible-range dyes, making it ideal for multicolor fluorescence detection in microscopy, flow cytometry, Western blotting, and in vivo imaging.
