Figure 5From: Evaluation of the Pichia pastoris expression system for the production of GPCRs for structural analysisSolubilization and purification of CHRM2 from P. pastoris. In each step of the purification process, CHRM2 was subjected to a specific binding assay (A) and CBB staining after SDS-PAGE (B). The specific binding assay was performed using the membrane fraction (memb.), solubilized fraction (sol.), TALON elution fraction (Co elution), and ConA flow-through fraction (ConA FT). Lanes 1-3 indicate fraction numbers 1-3 of the TALON elution. Lane 4 indicates the ConA flow-through fraction.Back to article page
