CuFi-8 cells differentiate on collagen-coated, semipermeable membrane inserts (0·6 cm2, Millicell-PCF; Millipore, Billerica, MA) into an air-liquid interface culture. After 3–4 weeks of culture in DMEM:F12 medium (50%:50%) containing 2% Ultroser G (Pall BioSepra, Cergy-Staint-Christophe, France) the polarity of the HAE was determined based on the transepithelial electrical resistance (TEER) using an epithelial Volt-Ohm Meter (Millipore). HBoV1 infection was performed at minimal values of 600–800 Ω per insert [27 (link)].
