Rekombinant BDNF som inneholder en Avi-sekvens (BDNFAvi) produseres i HEK293-celler på en kostnadseffektiv måte og renses av affinitetkromatografi. BDNFavi blir deretter direkte mono-biotinylert med enzymet BirA i et rør. BDNFavi og mono-biotinylated BDNFavi beholder sin biologiske aktivitet sammenlignet med kommersielt tilgjengelig BDNF.
