Translocation of IL-15 into the ER is IL-15Rα independent. (A) Western blot analysis of cell lysates from COS-7 cells transfected with IL-15 or IL-15 and IL-15Rα. (B) Western blot analysis of cell lysates from COS-7 cells transfected with IL-15 or IL-15 and IL-15Rα. Before analysis, the cell lysates were incubated alone (−), with Endo F, or with Endo H.
