查询词典 plasmid

AIM: To construct the eukaryotic expressing vector of human cbl and test its expression in African green monkey kidney cell line COS 7. METHODS: Human cbl gene tagged with flag was amplified from pEFHAcbl plasmid by PCR. The product was cloned into pGEM T easy, sequenced and then subcloned into eukaryotic expressing vector pcDNA3.1.
