Application

Biotin (5-fluorescein) conjugate is a reagent that may be used in situations similar to fluorescein isothiocyanate staining to label avidin/streptavidin conjugated molecules such as antibodies with the fluorophore 5-fluorescein.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Biotin-fluorescein conjugate for the fluorometric, accurate measurement of avidin and streptavidin.
Often referred to as Biotin (4-fluorescein) conjugate.
