Min at 4 C. Protein concentration of the supernatant was determined with a Pierce BCA Protein Assay Kit (Thermo Scientific, Rockford, IL, USA). A volume of supernatant that contained 100 ug of protein was removed, decreased, and alkylated. Ten microliters of 200 mM tris (2-carboxyethyl) phosphine (TCEP) diluted with 50 mM triethylammonium bicarbonate (TEAB) was added to every single sample and incubated at 55 C for 1 h even though mixing. Ten microliters of 375 mM iodoacetamide was added and incubated in the dark at area temperature for 45 min while mixing. Proteins had been precipitated overnight at -20 C with 880 of ice-cold acetone. The samples have been centrifuged at 15,000g for 20 min at 4 C. The supernatant was decanted, and samples were de-lipidated by adding 1 mL of ice-cold (tri-n-butylphosphate/acetone/methanol, 1:12:1) [15] and incubated for 90 min on ice. The samples were centrifuged at 2800g for 15 min at four C. The supernatant was removed and 1 mL of ice-cold tri-n-butylphosphate was added. The samples were centrifuged againInt. J. Mol. Sci. 2021, 22,20 ofunder precisely the same situations as previously stated. The supernatant was removed and 1 mL of ice-cold acetone was added. Centrifugation was repeated and also the supernatant removed. 1 milliliter of ice-cold methanol was added along with the samples were centrifuged to get a final time. The sample pellets were air-dried and resuspended in 12.five of eight M urea. Four mg of trypsin in 50 mM TEAB was added to every single sample and incubated for 24 h at 37 C. The samples were desalted using C18 Sep-Pak Vac 1cc cartridges attached to a vacuum manifold. The cartridges had been equilibrated using 3 1 mL aliquots of acetonitrile at a flow rate of 2 mL/min. The cartridges had been washed/equilibrated with three 1 mL aliquots of 0.25 trifluoroacetic acid. Trifluoroacetic acid was added towards the samples to bring them to a final concentration of 1 . The samples have been loaded on to Sep-Pak cartridges and allowed to pass by way of gravity flow. The cartridges had been washed with 4 1 mL aliquots of 0.25 Int. J. Mol. Sci. 2021, 22, x FOR PEER Review 17 of 31 trifluoroacetic acid. The peptides have been eluted in 1 mL of 80 acetonitrile/0.1 formic acid by gravity flow and dried inside a SpeedVac Concentrator.Figure four.
