To obtain transformed silkworm cell line stably expressing LTB, researchers fused the LTB coding sequence, neomycin-resistance gene (NeoR) and gfp gene into piggyBac-based transponson vector and transduced into silkworm BmN cells. After screening against antibiotic G418, the positive rate of cells emitting green fluorescence was 70.79%. PCR detection indicates the existence of exogenous LTB coding sequence, NeoR and gfp in the transformed cell genome. Western blot analysis also confirms the predicated ~60 kDa band of LTB protein. These results demonstrated that the strategy was practicable. ER -
