Summary

Automatic Translation

Genetisk kode ekspansion anvendes til indførelse af en unaturlig aminosyre forsynet med en biorthogonal funktionel gruppe på et bæreprotein på et defineret sted. Den biorthogonale funktion anvendes yderligere til den stedselektive kobling af et kulhydratantigen for at give en homogen glykokonjugavaccine.
