Expression of nAChR subunit protein by BEAS2B and IB3-1. Immortalized bronchial epithelial cell lines BEAS2B and IB3-1 were immunoblotted for nAChR. For each subunit, the positive control band was seen at the following size: α1 55 kD, α2 60 kD, α3 60 kD, α4 70 kD, α5 53 kD, α7 56 kD, β1 59 kD, β2 57 kD, and δ55 kD.
