Biotinidase

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.
