| | BIOTIN-4-FLUORESCEIN Usage And Synthesis |
| 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. |
