查询词典 mutant

The mutant △RSD-9 K141D was subcloned into the pGEX-6p-1 expression vector and the △RSD-9 protein was purified by GST affinity chromatography and digested by Prescission Protease to cut the GST domain. Next, to further verify the intracellular interaction of RSD-9/△RSD-9 and rtSH3p13 proteins, laser confocalization study and co-immunoprecipitation method were used.
