The decrease in the absorbance at 340 nm, caused by the oxidation of NADH, is a measure of the enzyme activity. Note: DL-8,6-Thioctic Acid is the same as DL-a-Lipoic Acid and the same as DL-1,2-Dithiolane-3-pentanoic Acid.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003e\u003cu\u003eApplications\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe enzyme occurs in mammalian and microbial cells and it catalyzes a number of reactions which involve NAD+ or NADH. Lipoamide dehydrogenase from porcine heart contains two polypeptide chains which are similar. It has two molecules of tightly bound flavin adenine dinucleotide (FAD). The molecular weight of the porcine heart enzyme is between 100,000 and 114,000.\u003c\/p\u003e\n\u003cp\u003e\u003c!--TBP0078-100U TBP0078-500U--\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 13px; font-weight: 700; text-transform: uppercase;\"\u003e\u003cstrong\u003eResearch use only.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/tribioscience.com\/wp-content\/uploads\/2026\/03\/TBP0078-Lipoamide-Dehydrogenase_Datasheet-1.pdf\"\u003eDatasheet (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/tribioscience.com\/wp-content\/uploads\/2024\/03\/TBP0078_Lipoamide-Dehydrogenase-Safety-Data-Sheet-1.pdf\"\u003eMSDS (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TriBioScience","offers":[{"title":"100 U","offer_id":45986499919951,"sku":"TBP0078-100U","price":0.0,"currency_code":"ILS","in_stock":true},{"title":"500 U","offer_id":45986499952719,"sku":"TBP0078-500U","price":0.0,"currency_code":"ILS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/0748\/5519\/files\/TBP0078-1.jpg?v=1782812663","url":"https:\/\/www.danyel.co.il\/products\/lipoamide-dehydrogenase-enzyme-activity-tbp0078","provider":"danyel biotech","version":"1.0","type":"link"}
