RAB11A and non-small cell lung carcinoma: Total proteins from these cells were extracted, and immunoprecipitation with a monoclonal antibody against EGFR followed by immunoblotting with antibodies against CMTM6, RAB7, and RAB11 showed that all of the examined proteins were efficiently co‐immunoprecipitated with EGFR from extracts of all examined NSCLC cell lines (Figure 1C).
