Abstract
To establish an rat basophil leukemia(RBL)-2H3 cell line stably expressing human high affinity receptor containing alpha, beta and gamma chain(hFcεRIαβγ), in order to provide experimental materials for evaluating allergenicity of food. The lentivirus was transfected into RBL-2H3 cells, and the mRNA expression of hFcεRIαβγ in cells was detected by real-time PCR and the protein expression of hFcεRIα was detected by flow cytometry. Sequencing result showed that recombinant lentiviral vector GV367-hFcεRIαβγ was successfully constructed. According to the result of experiments, lentivirus could effectively infect RBL-2H3 cells. The mRNA of hFcεRIαβγ and protein levels of hFcεRIα in RBL-2H3 cells were successfully overexpressed. The hFcεRIαβγ/RBL-2H3 cells were preliminarily constructed, which could be binded with human IgE and further used in the evaluation system of food allergy, compared to RBL-2H3 cells.
