invA Plasmid

invA Plasmid

Contribution

InvA, which is essential for Salmonella spp. to enter cultured epithelial cells, is a member of a family of proteins involved in either flagellar biosynthesis or the secretion of virulence determinants by a number of plant and mammalian pathogens. We designed this plasmid by inserting InvA 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 InvA containing plasmids

We send the company to synthesize the DNA fragments of InvA, 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.

Figure 1. the sequencing data of InvA DNA fragment.
