E. coli strains
SSI Diagnostica Group provides well-characterized E. coli reference strains to support serotyping, vaccine and assay development as well as quality control across research, surveillance and industrial microbiology.
Product description
The bacterial strains of SSI Diagnostica Group are mostly clinical isolates. E. coli strains are delivered in extract agar in either a sealed glass tube or in a cryogenic vial. Strains sent in agar slant must be plated out within a week from receipt and resown, as strains cannot survive in transport agar for a long time.
Each strain has been grown on a non-selective agar plate overnight and the serotype verified by SSI Diagnostica Group’s specific antisera.
How to use
The bacterial strains of SSI Diagnostica Group are intended for research or for use as negative / positive controls for serotyping of antigens. The strains sent in agar slant can be cultured directly.
