Protein expression of α1 in HEK293 cells. (a) Expression of total α1 protein was detected in HEK293 cells transfected with wild-type or mutant human α1β3γ2 cDNAs (ratio 1:1:5). Protein levels were normalised to GAPDH expression. (b) Representative western blot analysis (n = 3). 1: 20 µg mouse Hippocampus, 2: 20 µl untransfected HEK293 cells, 3–5: 20 µl HEK293 α1A332Vβ3γ2, 6–8: 20 µl HEK293 α1β3γ2; bg1: background signal for green channel (α1), bg2: background signal for red channel (GAPDH). (c) Immunostaining of surface α1 expression (red). Both mutated and wild-type subunits appear at cell surfaces when co-expressed with β3 and γ2 subunits.
