ipaH Plasmid

ipaH Plasmid

Contribution

Shigella is a class of non-spore-forming Gram-negative pathogens whose pathogenicity depends on the secretion system. Shigella ipaH family proteins are co-encoded by virulence large plasmids and genes on chromosomes. We designed this plasmid by inserting ipaH DNA fragment into the plasmid pUC57 with a T7 promoter and terminator in front and after the sequence. This plasmid is used to obtain the gene fragment of Shigella which will bind with sgRNAs and recruit cas12a protein to cleave the DNA fragment of it.

Construction of the gene ipaH containing plasmids

We send the company to synthesize the DNA fragments of ipaH, and inserted it into the pUC57 vector, the sequenced data showed that the plasmids which were provided by the company were successfully constructed (Figure 1). The constructed plasmids were contained in E. coli strains, we streak inoculated them on LB solid medium plates containing corresponding antibiotics, and incubate them at 37℃ overnight, then we extracted the plasmids.
