Il BDNF ricombinante contenente una sequenza Avi (BDNFAvi) viene prodotto nelle cellule HEK293 in modo conveniente ed è purificato dalla cromatografia di affinità. BDNFavi viene quindi direttamente mono-biotinylated con l'enzima BirA in un tubo. BDNFavi e BDNFavi monobionlate mantengono la loro attività biologica rispetto al BDNF disponibile in commercio.
