Summary

Automatic Translation

Biochemische und strukturelle Analysen des glykosylierten Proteinen erfordern relativ große Mengen an homogenen Proben. Hier präsentieren wir Ihnen eine effiziente chemische Methode für standortspezifische Glykosylierung von rekombinanten Proteinen durch gezielte reaktive Cys Thiole von Bakterien gereinigt.
