Menaquinone 9 (Standard)

Customer Review

Based on 1 Customer Validation

Menaquinone 9 (Standard) is the analytical standard of Menaquinone 9 (HY-131501). This product is intended for research and analytical applications. Menaquinone 9 is a naphthoquinone-type vitamin K and electron transport component produced by bacteria. Menaquinone 9 is an orally active analog of Vitamin K2 (HY-109569). Menaquinone 9 acts as an ultraviolet-sensitive, photooxidizable substrate that generates more polar photodegradation products under oxygen and ultraviolet irradiation. Menaquinone 9 binds to the αβ dimer of Escherichia coli nitrate reductase, supporting electron transport within the αβ subunit structure of the enzyme. Menaquinone 9 serves as a precursor for bone Menaquinone-4 (HY-B2156). Menaquinone 9 can be used in studies related to metabolic diseases.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
