Abstract:
OBJECTIVETo study the membrane mobility of aquaporin 7 (AQP7) by cloning stably transfected CHO cells with expression of pEGFP-C1-AQP7, in which AQP7 cDNA was fused downstream and in frame to pEGFP-C1 gene.
METHODSThe full sequence of AQP7 was amplified by RT-PCR and then recombined in the downstream of the green fluorescent protein gene in the pEGFP-C1 vector. The recombinant vector pEGFP-C1-AQP7 was stably transfected into CHO cells. With fluorescent microscopy, immunocytochemical stain and Western blot, pEGFP-C1-AQP7 showed a predominant intracellular vesicular localization.
RESULTS(1) The sequence of AQP7 cDNA of the Wistar rat was logged into the GenBank (access number: AY157737). (2) Identification demonstrated that pEGFP-C1-AQP7 fusion protein stably expressed in CHO cells. (3) With fluorescence microscopy, pEGFP-C1-AQP7 showed a predominant intracellular vesicular localization.
CONCLUSIONThe CHO cell line with stable pEGFP-C1-AQP7 expression was set up successfully for advanced research.
