BIOTIN-4-FLUORESCEIN Chemical Properties,Uses,Production
Uses
Biotin-4-Fluorescein is used to quantitate biotin binding sites. Biotin-4-Fluorescein is a reagent that binds to avidin more readily than conventional fluorescein biotin.
Biological Activity
Biotin-fluorescein is mainly used for the assay of biotin-interaction sites in avidin and streptavidin. Binding of biotin-4-fluorescein results in strong quenching, which is used for measuring the concentration of (strept)avidin.
