查询词典 purification

However, opioid receptors are not expressed naturally in great abundance, they are relatively labile and frequently difficult to solubilize as monomers. The availability of their cDNAs makes them good candidates for overexpression in heterologous cells, which offers hope for the purification of membrane receptors for biochemical and structural studies.
