ShigaToxType AS-2 Kit

(item number 245900096)

Identify the Shiga toxin 1 and 2 subtypes

The assay allows rapid, economic and standardized DNA-based subtyping of all known Shiga toxin subtypes (Stx variants classified according to the nomenclature of Scheutz et al. 2012) directly from colony material in a short time. Furthermore, the identification of both, single and multiple Stx subtypes within a clonal isolate is feasible.

Assay Principle

Family, genus and species controls

Family, genus and species specific markers were included to identify Enterobacteriaceae (Shigella spp. / EIEC or Escherichia coli) and distinguish them from other species which might contaminate the sample (Citrobacter freundii/braakii, Salmonella spp., Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii).
