From: Expression of G-protein inwardly rectifying potassium channels (GIRKs) in lung cancer cell lines
GIRK1 protein expression in SCLC cells that express GIRK1 mRNA as assessed by western blot analysis. In the three SCLC cell lines that expressed GIRK1 mRNA (Figure 1), membrane protein expression was determined. Top panel: All three SCLC cell lines (WBA, H69, H146) expressed GIRK1 membrane protein. Bottom panel: Actin was used as a control for equal sample loading. The bands are consistent with the expected size: GIRK1-62 kDa; actin-42 kDa.
