Title	Large-scale Proteomics Profiling of Peripheral Blood of DM1 patients identifies biomarkers for disease severity and functional capacity
Description	3 µl of each human serum sample was added to 40 µl lysis buffer containing 5% sodium dodecyl sulfate (SDS) and 50 mM triethylammonium bicarbonate (TEAB), pH 8.5. Proteins were reduced by addition of 15 mM dithiothreitol and incubation for 30 minutes at 55˚C and then alkylated by addition of 30 mM iodoacetamide and incubation for 15 minutes at RT in the dark. Phosphoric acid was added to a final concentration of 1.2% and subsequently samples were diluted 7-fold with binding buffer containing 90% methanol in 100 mM TEAB, pH 7.55. The samples were loaded on the 96-well S-Trap™ plate (Protifi), placed on top of a deepwell plate, and centrifuged for 2 min at 1,500 x g at RT. After protein binding, the S-trap™ plate was washed three times by adding 200 µl binding buffer and centrifugation for 2 min at 1,500 x g at room temperature. A new deepwell receiver plate was placed below the 96-well S-Trap™ plate and 50 mM TEAB containing trypsin (1/100, w/w) was added for digestion overnight at 37°C. Using centrifugation for 2 min at 1,500 x g, peptides were eluted in three times, first with 80 µl 50 mM TEAB, then with 80 µl 0.2% formic acid (FA) in water and finally with 80 µl 0.2% FA in water/acetonitrile (ACN) (50/50, v/v). Eluted peptides were dried completely by vacuum centrifugation. Dried peptides were redissolved in 100 µl 0.1% FA, the peptide concentration was determined on a Lunatic spectrophotometer (Unchained Labs) and was adjusted to 0.015 µg/µl with 0.1% FA1. iRT peptides (Biognosys, P/N Ki-3002-1) were added to all samples according to the manufacturer’s instructions. Then, 300 ng of each sample was loaded on Evotips (Evosep, P/N EV2003) according to the manufacturer’s instructions with a substitution of the wash step after sample loading by two wash steps with 80 µl 0.1% FA. All loaded Evotips were stored in 0.1% FA at 4°C until LC-MS/MS analysis was started.
