Information
B-One® is designed for high-throughput laboratories that use automated liquid handling instruments. It provides the most efficient hydrolytic activity at room temperature for the broadest spectrum of conjugated analytes.
This enzyme cleaves codeine-6-glucuronide, dihydrocodeine-6-glucuronide, and other “hard-to-cleave” drug conjugates. It is stabilized in its reaction buffer and hydrolyzes at room temp to save buffer preparation and heating steps; enabling toxicology laboratories to eliminate bottlenecks in sample preparation, and permitting automated hydrolysis and same-day results.
B-One® achieves reliable results for high-throughput clinical, forensic, workplace drug testing, and other kinds of laboratories, obtaining complete recoveries as fast as instant to 15 minutes. Samples are ready to analyze in minutes following a simplified Hydrolyze-Analyze™ concept. Because of its high purity, it is free from secondary enzymes and small contaminant molecules to eliminate interferences and unwanted conversions.
This unique enzyme does not require supplemental buffering – its “all-in-one” formula allows you to simply add B-One® and ISDs to the urine samples; no additional reagent mixing or cleanup is needed.
