Product Overview:
Tween ® 80 Tween ® 80 is a non-ionic detergent that is provided for research purposes or as a 10% proteomic grade solution. Proteomic Grade: DG013, DG014, DG513, DG520 Research Grade: 786-519, 786-520 Proteomic Grade Detergent Solutions Many commercial grade detergents contain elevated levels of sulfhydryl oxidizing agents, peroxides, salts and carbonyl compounds. The proteins that are isolated with these detergents are highly susceptible to contaminating peroxides and carbonyls. The peroxides will oxidize proteins and the carbonyl groups will form Schiff's bases with the proteins that interfere with its structure. G-Biosciences' Proteomic Grade Detergent Solutions contain reduced peroxides and carbonyl compounds. In addition, the detergents have less than 50µS conductivity. These detergents are offered as 10% aqueous solutions, sealed under inert gas, and are suitable for protein applications. These non-ionic detergents are suitable for isolating membrane-protein complexes. Other Proteomic Grade Detergent Solutions offered include: Triton ® X-100, Triton ® X-114, Brij ® 35, Brij ® 58, Tween ® 20 and Nonidet ® P-40 Substitute. A variety pack is also available, perfect for trial and optimization. The pack contains one 10ml vial of all seven proteomic grade detergents, as well as one gram samples of one of our Zwitterionic detergents (CHAPS) and one of our non-detergent sulfobetaines (NDSB 201).
Application:
Non-ionic detergent for solubilizing membrane proteins during isolation of membrane-protein complexes Ultra low concentrations of contaminating peroxides, aldehydes, salts and carbonyl compounds
