Western blot analyses of a sstr-expressing small cell lung carcinoma cell line (H69) lysate using the anti-sstr2 antibody [UMB-1] yielded three specific bands (Fig 3, lane sstr2), while that using the anti-sstr5 antibody [UMB-4] yielded a single band (Fig 3, lane sstr5). This evidence concerns the gene SSTR5 and small cell lung carcinoma.
