Abstract:
1. A method for production of a hemagglutinin-neuraminidase (HN) polypeptide, wherein said HN polypeptide is glycosylated and comprises full length HN polypeptide, a membrane domain and a native HN signal peptide, said method comprising culturing a recombinant microalgal host cell in a medium, wherein the recombinant microalgal host cell comprises a heterologous nucleic acid molecule comprising the sequence of SEQ ID NO:1 encoding the HN polypeptide to produce the HN polypeptide, and wherein the microalgal host cell is free of polynucleotide sequences encoding other heterologous viral polypeptides, whereby the HN polypeptide is secreted into the medium by action of the signal peptide, and recovering the HN polypeptide from the medium.
