谷胱甘肽转移酶

GultathioneStransferases 谷胱甘肽转移酶 

Glutathione S-Transferase from equine liver

lyophilized powder, ≥25 units/mg protein

谷胱甘肽转移酶Description

Analysis Note Protein determined by biuret.

Purified and assayed by a modification of the method of Simons and Vander Jagt.

Enzymatic activities are based on the conjugation of reduced glutathione with a second substrate. The individual proteins generally have activity with more than one class of substrate.

Unit Definition One unit will conjugate 1.0 μmole of 1-chloro-2,4-dinitrobenzene with reduced glutathione per min at pH 6.5 at 25°C.

Physical form Lyophilized powder containing Tris and phosphate buffer salts, reduced glutathione and EDTA
