To assess the GSSG fraction, first, thiol groups of GSH are blocked with N-ethylmaleimide (NEM) in a subsample, followed by removal of excess NEM with toluene prior to reduction of GSSG to GSH with DTT and derivatization via mbrB (Kranner 1998

2.5 Liver lipid metabolism-related enzymes activity Liver tissue samples were homogenized (motor-driven Teflon glass homogenizer, Thomas Scientific Swedesboro, NJ, USA) in an ice-cold buffer [9 mM KH 2 PO 4 , 85 mM K 2 HPO 4 , 1 mM DTT, and 70 mM KHCO 3 (pH 7.0)] and centrifuged at 100,000 g for 1 h at 4 C (LE80, Beckman Coulter, Palo Alto, CA, USA)

Four of the five warning letters were to companies (specifically, Xcel Research, Prime Vitality, Summit Research Peptides, and Swisschem) that claimed to distribute GLP-1s for research use only in spite of ample evidence to the contrary
