General description
4-Hydroxyazobenzene-2-carboxylic acid (HABA) is an avidin-binding dye that can be stoichiometrically displaced by biotin. The subsequent change in absorption at A500 provides a basis for spectrophotometric determination of biotin levels in biological samples.
HABA/Avidin Reagent is specific for chromogenic applications that depend upon quantification of biotin.
Application
HABA/Avidin Reagent is suitable for spectrophotometric determination of biotin and biotin conjugates in a wide variety of samples.
Reagent is capable of detecting biotin at μMolar concentrations (i.e., 1 nmole per ml). Typically used to quantitate biotin in biotinylated compounds.
Reconstitution
Prepares a ready-to-use HABA/avidin solution in buffered saline, pH approx. 7.3, with preservative when reconstituted with 10 ml deionized water.
