trans-Caffeic acid (Standard)

Customer Review

Based on 1 Customer Validation

trans-Caffeic acid (Standard) is the analytical standard of trans-Caffeic acid (HY-121231). This product is intended for research and analytical applications. trans-Caffeic acid is a hydroxycinnamic acid widely distributed in coffee, propolis, and Lamiaceae herbs. trans-Caffeic acid exhibits significant antioxidant and photoprotective activities, and can be used in cancer-related research. trans-Caffeic acid readily undergoes reversible isomerization to form its cis-isomer in protic solvents, under high temperature, ultraviolet radiation, and stress conditions. Binding of trans-Caffeic acid with aluminum, lead, or copper ions attenuates isomerization and inhibits the formation of vinylcatechol, while complexation with lead or copper ions also promotes the formation of aesculetin.

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.
