In Vitro

Daidzin inhibits hamster and rat ALDH-2, with K_is of 0.082 and 0.052 μM respectively^[1].
Daidzin (500 μM) shows antioxidant activity, measured by its ability to inhibit cytochrome c reduction by Phorbol myristic acetate (PMA)-stimulated neutrophils^[3].
Daidzin (0-30 μM, 30 min) inhibits the formation of 5-HIAA (IC₅₀ value of ≈2.7 μM), and increases the amounts of 5-HIAL and 5-HTOL in the incubation media of hamster liver mitochondrial^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Daidzin (30 mg/kg, intragastrically) decreases blood alcohol levels (induced by 3 g ethanol/kg body weight), and shortens sleep time induced by Ethanol intoxication (7 g/kg by intubation) in fasted rats^[3].

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.
