Strep-Tactin Superflow high capacity columns (1 mL, IBA lifescience) run in 20 mM HEPES, 300 mM NaCl pH 7.5 were used for further purification. After a column wash, the protein was eluted using the same buffer supplemented with 2.5 mM desthiobiotin. TEV-cleaved DARPin NY_1 was reverse-purified via IMAC and the monomer was isolated from Superdex 200 equilibrated in 20 mM HEPES, 150 mM NaCl pH 7.5. For cross-linking, HLA-A0201/NY-ESO1157-165(9V) was mixed in a 1:2 molar ratio with NY_1, concentrated to an absorbance at 280 nm (Abs280) of 2.3, and incubated for 45 min in 25 mM HEPES, 150 mM NaCl, supplemented with 1.4 mM BS(PEG)5 (BS5) (ThermoScientific). The cross-linker was quenched by addition of 25 mM Tris. Samples for grid screening were isolated from Superdex 200 GL 10/300 SEC in 25 mM HEPES, 150 mM NaCl, pH 7.4, and concentrated to Abs280 values of 2. Entity ID: all / 由来: RECOMBINANT |
