Fig. 1: SCT production and quality control.

a Workflow of SCT production. Reduced SDS-PAGE gel showing expressed SCT protein (~50 kDa); SN supernatant, P His-Tag purified SCT. b Cell viability and transfection efficiency of SCT plasmid library. c SCT yield from each peptide element of the SCT plasmid library, with or without IRES-GFP reporter. Error bars represent standard deviation, n = 3 independent measurements. d Reduced SDS-PAGE gel of A*02:01 and A*24:02 SCTs pre- and post-PNGase treatment. NXT glycosylation motifs of peptides are underlined.
