Allows the measurement of the molar ratio of biotin to protein in biotin-protein conjugates, biotin-DNA molar ratios in biotinylated DNA samples, or quantitation of biotin concentrations in solution.

This assay employs the sensitive chromogenic reagent 4'-hydroxyazobenzene-2-carboxylic acid (HABA) that exhibits a UV spectral absorbance at 500 nm when bound to avidin. Because biotin easily displaces HABA from HABA/Avidin complexes, the resulting decrease in absorption at 500 nm can be used to sensitively measure biotin concentrations.

Technical Data
SKU M1356
Unit Size 1kit
Absorption 500nm
Notes The kit can be used to determine biotin concentrations down to 1 uM concentrations. Includes enough reagents for 100 assays using a microtiterplate format (96-well plate, 200uL assay volume) or 20 assays using a spectrophotometer (1mL assay volume).
