We have determined that RCAN1-1L is expressed at twice the level of RCAN1-4, and that there is very minor expression ... As this antibody is generated against a pep- tide present in both RCAN1-1 isoforms, it recognizes both bands. RCAN1-1S was the minor band, which was very weak and difficult to detect and quantify.
