Chem-1 cells are an adherent cell line endogenously overexpressing Gα15 and are used as a host for ChemiScreenTM GPCR Membrane Preparations. ChemiScreenTM Wild-Type Chem-1 Membrane Preparations are ideal controls for validation of radioligand binding assays employing ChemiScreenTM GPCR Membrane Preparations in the Chem-1 host cell line.
