  • Construction Eukaryotic Expression Vector of Human CD59 and Transfection NIH3T3 Cells by Chitosan Encapsulate

    【Abstract】ObjectiveTo construct eukaryotic expression vector pSecTag2/HygroB-CD59 of human CD59 and transfect NIH3T3 cells after encapsulated by chitosan. MethodsThe human CD59 fragments were obtained by PCR form CD59-pGEM-T Easy Vector, cloned into the eukaryotic expression vector pSecTag2/HygroB, identified by restriction endonuclease’s digestion and DNA sequencing. After the particles of pSecTag2/HygroB-CD59 were encapsulated by chitosan, the NIH3T3 cells were transfected by chitosanCD59 nanoparticles and detected CD59 expression by immunohistochemistry stain. ResultsThe CD59 fragment was 312 bp. Its sequence was as same as CD59 cDNA in Genbank. After having been transfected by chitosan-CD59 nanoparticles in 24 hours, the 3T3 cells showed diffusely positive in the cytoplasms by anti-CD59 immunohistochemistry. ConclusionThe eukaryotic expression vector of human CD59 is constructed and transfected to NIH3T3 cells after encapsulated by chitosan. It will be very helpful for further study on transgenic livers.
