meso-Astaxanthin

meso-Astaxanthin is a natural stereoisomer of Astaxanthin (HY-B2163) with antioxidant activity and is found in a variety of aquatic animals. meso-Astaxanthin binds to human serum albumin in a monomeric form at a stoichiometric ratio; at low ligand-to-protein ratios, human serum albumin acts as a chiral template for supramolecular assembly at higher ratios. meso-Astaxanthin directly scavenges superoxide anions. meso-Astaxanthin can be used in the research of myocardial ischemia-reperfusion injury.

Biological Activity

Description

In Vitro

meso-Astaxanthin (100 μM) exhibits equivalent superoxide anion scavenging activity in human neutrophil assays compared with other astaxanthin stereoisomers^[1].
meso-Astaxanthin (1:1 molar ratio) binds stoichiometrically to human serum albumin (HSA) at the interdomain cleft in pH 7.4 buffer^[1].

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.
