AB - The non-toxic B subunit of Escherichia coli heat-labile
enterotoxin (LTB) is a potent mucosal immunogen and immunoadjuvant for coadministered
antigens. 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.
