Bacterial polysaccharides are utilized in vaccines and inflammatory challenge models to trigger the body’s natural immune system inducing a robust and broad immune response. The response is harnessed in vaccines to protect against a wide range of infectious and immune mediated diseases. List Labs has a wealth of experience manufacturing bacterial polysaccharide products for research, vaccine development, and for use in clinical trials. Our extensive experience includes custom client preparations of crude polysaccharide extracts for vaccine development to our highly purified GMP lipopolysaccharide for clinical trials, which has been used by major pharmaceutical companies and universities, as well as the NIH Clinical Center. We have proprietary chromatography methods to effectively remove traces of proteins and nucleic acids for an ultra-pure LPS product, known as HPTTM LPS. Our experience includes preparations from an extensive list of bacterial organisms including Escherichia coli, Salmonella minnesota, Salmonella typhimurium, Bordetella pertussis, and Clostridium difficile.
