AVAILABLE TO ORDER
GRADE & PURITY Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. Recombinant ? Recombinant — produced via recombinant expression for defined sequence and consistency. Use for reproducible, animal-free proteins of known origin. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. EnzymoPure™ ? EnzymoPure™ — Aladdin's line of high-quality enzymatic solutions. Use when enzyme purity and defined activity drive assay or process performance. ≥100U/mg enzyme powder; ≥250U/mg protein

Overview

  Lactate oxidase catalyzes the oxidation of lactate to pyruvate and hydrogen peroxide in the presence of an FMN co-factor. The enzyme aids in the determination of L-lactate indirectly by measuring the hydrogen peroxide formed in the reaction.
