ExpreS2ion Biotechnologies: ExpreS2ion announces poster presentation on the use of glycoengineered Drosophila S2 cells for production of highly immunogenic antigens at the ESACT meeting
Hørsholm, Denmark, 24 June 2024 - ExpreS2ion Biotech Holding AB's affiliate ExpreS2ion Biotechnologies ApS ("ExpreS2ion") today announces that the company presented a poster on the use of glycoengineered Drosophila S2 cells for production of highly immunogenic antigens, at the European Society for Animal Cell Technology (ESACT) bi-annual meeting, taking place 23-26 June 2024, in Edinburgh, Scotland.
Modified recombinant antigens with high-mannose or xylosylated N-glycans produced significantly higher antibody titers in immunized mice compared to antigens with S2 wildtype N-glycans.
Although presenting antigens on virus-like particles substantially enhances immunogenicity, a similar effect can be achieved through glycomodification of the soluble antigen.
Both approaches resulted in high antibody titers and their neutralizing capabilities were shown in the virus neutralisation assay for high-mannose antigen.
