GRADE & PURITYBioactive?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.≥90%(SDS-PAGE)≥20U/mg enzyme powder; ≥35U/mg protein

Descripción general
A flavoprotein. The enzyme catalyses a two-electron reduction and has a preference for short-chain acceptor quinones, such as ubiquinone, benzoquinone, juglone and duroquinone. The animal, but not the plant, form of the enzyme is inhibited by dicoumarol.
