Thermo Scientific Pierce Biotin Quantitation Kit
HABA dye reagent and biotinylated protein standard for convenient colorimetric determination of biotinylation levels in antibodies and other proteins.
Manufacturer: Thermo Scientific 28005
Thermo Scientific Pierce Biotin Quantitation Kit includes aliquots of HABA reagent and biotinylated protein standard for convenient colorimetric determination of biotinylation levels in labeled antibodies and other proteins.
Determine the molar ratio of biotin incorporated into a protein using the HABA-avidin method. The HABA dye (4'-hydroxyazobenzene-2-carboxylic acid) binds to avidin to produce a yellow-orange colored complex that absorbs at 500nm. Free biotin present in solution with this avidin-HABA complex will displace the HABA dye and cause the absorbance to decrease.The amount of biotin present can be calculated directly from the decreased absorbance at 500nm. The Thermo Scientific EZ Biotin Quantitation Kit contains pre-measured doses of the Avidin-HABA mixture and biotinylated horseradish peroxidase positive control to simplify reagent preparation and minimize the amount of waste generated. The convenient assay can be performed either in a cuvette or in a microplate.
- HABA-avidin complex can be used over a wide range of pH and salt concentrations
- Amount of biotin can be calculated directly from the decreased absorbance at 500nm complexing with the HABA dye
Eliminate the need for cumbersome assay equations with a convenient HABA calculator found at www.piercenet.com/HABA/habacalc.cfm
