Case Study

GPCR overexpression cell line facilitates new drug development

The expression level of GPCR in vivo is low and the effect of conventional overexpression is not sufficient, which is not conducive to the study of GPCR structure and function. With protein engineering and sequence optimization, we are able to significantly increase the expression level of ADORA2A protein on the cell surface.
