The latter is an amino donor of various nitrogenous substances such as proteins, nucleic acids and various coenzymes. As a conditionally essential amino acid for the human body, the production of glutamine has received extensive attention in recent years. GS catalyzes ammonium ion and glutamic acid to synthesize amide, and produces chromogenic substance under the action of invertase and chromogenic agent. The maximum absorption peak is at 570 nm. The activity of GS in samples is calculated by measuring OD value at 570 nm and standard curve.\u003c\/p\u003e\n\n\u003cp\u003eAbbreviation: GS\u003c\/p\u003e\n\n\u003cp\u003eResearch Areas:  Liver and Renal Function;Tricarboxylic Acid（TCA）Cycle\u003c\/p\u003e\n\n\u003cp\u003eResult Type: Enzyme activity\u003c\/p\u003e\n\n\u003cp\u003eDetection Instrument: Microplate reader\u003c\/p\u003e\n\n\u003cp\u003eDetection Type: Colorimetric method\u003c\/p\u003e\n\n\u003cp\u003eDetection Range: 0.04-49.54 U\/L\u003c\/p\u003e\n\n\u003cp\u003eTested Sample Types: Serum;Plasma;Animal tissue;cell\u003c\/p\u003e\n\n\u003cp\u003eAssay Length: 50 min\u003c\/p\u003e\n\n\u003cp\u003eSensitivity: 0.04 U\/L\u003c\/p\u003e\n\n\u003cp\u003eInter cv: 3.8%-9.8%\u003c\/p\u003e\n\n\u003cp\u003eIntra cv: 4.0%-5.0%\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"Elabscience","offers":[{"title":"96T","offer_id":46264326095027,"sku":"E-BC-K664-M-96","price":693.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/Screenshot_2024-02-12_153513_49a86b0b-f422-42b0-baac-7435bb35d3d6.png?v=1707826183","url":"https:\/\/afsbio.com\/products\/glutamine-synthetase-gs-activity-colorimetric-assay-kit-e-bc-k664-m","provider":"AFSBio Inc.","version":"1.0","type":"link"}
