Detection kit for transposable IS elements

Detection kit

The White Glove IS detection kit detects the presence of transposable Insertion Sequence (IS) elements in a DNA of interest. Numerous IS elements are naturally present in the genomes of E. coli strains commonly used for protein and plasmid production. IS element transposition is known to be stimulated by the cell stress response and can lead to the “hopping” of IS elements into plasmid DNA and or into other regions of the bacterial chromosome. The transposition of IS elements into an expression vector can interfere with the expression of a foreign protein in E. coli. IS element transposition can also contaminate pDNA isolated for vaccine purposes. The new detection kit can be used to detect the presence of IS elements in the genomes of commonly used E. coli strains. The kit can also be used to determine which elements have transposed from these genomes into a plasmid of interest propagated in these strains.
