GRADE & PURITY Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. Native ? Native grade — protein/biomolecule in its natural (non-recombinant, non-denatured) form. Use when native structure and 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. ≥90%(SDS-PAGE) from Alcaligenes sp; ≥10 U/mg enzyme powder

Overview

In enzymology, a choline oxidase (EC 1.1.3.17) is an enzyme that catalyzes the chemical reaction: choline +O₂↔ betaine aldehyde +H₂O₂. Thus, the two substrates of this enzyme are choline and O₂, whereas its two products are betaine aldehyde and H₂O₂. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor.

 (CH₃)₃N⁺CH₂CH₂OH + H₂O + 2O₂→(CH₃)₃N⁺CH₂COO⁻ + 2H₂O₂
