Beta-cell Galphas signaling is critical for physiological and pharmacological enhancement of insulin secretion

ABSTRACT: Islet lysates were adjusted to 5 percent SDS in TEAB, pH 8.5, reduced and alkylated and digested with modified trypsin (Worthington) using an S-trap mini device (Protifi). Peptides were labeled with TMT16 reagents (lot ZH350094). Phosphopeptide enrichment used GL Sciences p10 TiO tips. LC-MS/MS used a MClass UPLC system (Waters) and Exploris 480 (ThermoFisher). Analytical separation used HSS T3 C18 75 micron by 250 mm column (Waters) with a 90 min gradient of 5 to 30 percent MeCN at a flow rate of 400 nl per min. Data collection on TMT-labeled samples was performed in data-dependent acquisition (DDA) mode with 2 FAIMS compensation voltages. TMT data was analyzed using Fragpipe 19.
