Expression of Sp17 protein on the surface of 2 myeloma cell lines.
The expression of Sp17 protein (ARP-1, upper panel; ARK-B, lower panel) is demonstrated by flow cytometry (2-stage cell-staining technique). Rabbit Sp17 polyclonal antiserum was used to stain the cells. Phosphate-buffered saline was used as a control.
