Reconstituted by adding 1.0 mL sterile distilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C.
Cross-reactivities against enzymes of other sources may occur but have not been determined.
Prior to use, an aliquot is thawed slowly at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at 4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the product.
The enzyme amino acid arylamidase catalyzes the hydrolysis of an N-terminal amino acid from arylamides. Substrates having amino acid residues with larger R groups, such as leucine, interact much more effectively with enzyme.
