| Abstract: | By molecular cloning method, full-length gene Ef was cloned into the downstream of the Ptac promoter of expression vector pGEX-6p-1, electric shock transformed into E. cohi BL21 (DE3) expression. After PCR amplification, and protein gel electrophoresis, the EF protein was effectively expressed, providing further construction of bio-engineering vaccine of Streptococcus suis serotype 2 with an initial vector. |
