Biotinidase activity is determined colorimetrically by measuring the amount of p-Aminobenzoic Acid (PABA) released from Biotinyl-p-Aminobenzoate (Biotin-PAB). Samples with biotinidase activity develop a purple color. Samples without biotinidase activity remain straw-colored.
Astoria-Pacific also supplies Dried Blood Spot Controls, Unassayed (Normal and Deficient) for Biotinidase and GALT testing. Use with your with SPOTCHECK Flow or Pro systems.
