Construction and identification of the recombinant hFcεRIα/RBL-2H3 cells

Publication date: Available online 10 September 2018Source: PlasmidAuthor(s): Zhongcheng Liu, Lifang Hao, Nanan Wang, Su Zhang, Nan Zhang, Zhenzhen Xu, Yanlei Yang, Yanfen ZhangAbstractIgE/FcεRI signal pathway plays a crucial role in triggering allergic reactions, and there is no cross-recognition between IgE and FcεRI in human and rats. In order to obtain the hFcεRIα/ RBL-2H3 cell line, total RNA was extracted from U937 cells, and the human FcεRIα gene was obtained by RT-PCR technology. Then the amplified product was digested and inserted into the pIRES2-EGFP vector. After the plasmid was transfected into the RBL-2H3 cells using lipofectamine, and the RBL-2H3 cell lines of stable expression were screened by G418. The transfection efficiency reached 60.45% with optimizing transfectio...
