Fig. 3

a Workflow for generation of the heterochiral d-Abl SH2:l-monobody complex. d-Abl SH2 was produced by solid-phase peptide synthesis (SPPS) and native chemical ligation (NCL) and the l-monobody by bacterial expression and subsequent purification. After mixing, the complex was purified by size exclusion chromatography (SEC). b, c Analytical SEC of complex formation between synthetic d-Abl SH2 and recombinantly expressed (b) l-DAM21 and (c) l-DAM27. d Preparative SEC of d-Abl SH2:l-monobody complexes generated for crystallization condition screening. All chromatograms include a calibration of the column with standard proteins on top. e Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of the complex formation (performed once). Source data of (e) are provided as a Source Data file.
