Hydroxytyrosol acetate

Customer Review

Based on 1 Customer Validation

Hydroxytyrosol acetate is an orally active, blood-brain barrier-permeable multi-active compound with multiple effects including antibacterial, antioxidant, anti-platelet aggregation, and neuroprotective activities. Hydroxytyrosol acetate not only inhibits the growth of Vibrio by increasing bacterial membrane permeability, but also interacts with DNA and mediates supercoiled DNA relaxation. Meanwhile, Hydroxytyrosol acetate effectively reduces thrombosis and inhibits lipid oxidation by inhibiting COX activity and promoting vascular nitric oxide production. In terms of neuroprotection, Hydroxytyrosol acetate significantly alleviates neuronal apoptosis and inflammatory responses by up-regulating the expression level of ERβ, thereby improving cognitive function in Alzheimer's disease models. Hydroxytyrosol acetate has been widely used in scientific research related to Vibrio infection, arterial thrombosis, Alzheimer's disease and other related fields.

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.
