The correct washes were vacuum-concentrated and pooled to resuspension in 0 prior.5% (v/v) formic acidity and desalting using Empore 1 mL SPE cartridges (Sigma). (S7; 50% launching) discovered 20, 11 which had been common towards the control beads. The dependability of bead pull-downs was analyzed in duplicate tests using two separately synthesized batches each of S1 and S2. Bead S1 demonstrated high similarity in the overall amounts of PKs discovered across two tests, at 40 and 35 PKs, which 26 had been common over the two batches of beads, with 14 and 9 exclusive PKs discovered in each test. The S2 beads extracted 61 and 64 PKs with 55 PKs common over the two bead batches analyzed.
