Expanding the range of bioconjugate vaccines to fight more bacterial threats

https://omniose.com/wp-content/uploads/2020/06/home_hero_detail.jpg

Omniose is an early-stage biotechnology company developing polysaccharide conjugate vaccines against serious bacterial threats using its proprietary bioconjugation platform.

We are expanding the range of bacterial targets that can be addressed with bioconjugate vaccines. Bioconjugation relies on single cells that simultaneously produce a polysaccharide antigen along with an engineered carrier protein and a conjugating enzyme to precisely link them together. This is a much simpler process than conventional chemical conjugation methods and has the potential to produce higher quality vaccines. However, the enzymes used for bioconjugation thus far could only address a limited range of bacterial targets.

Our platform enables the precise enzymatic attachment of virtually any bacterial polysaccharide (sugar) antigen to engineered carrier proteins within a single E. coli cell. Hence the name Omniose, “all sugars”.
