Fig. 5. Generation of stable IMCD cell populations expressing CD98 or CD98 deletion mutants. IMCD cells were transfected with the full-length or deletion CD98 constructs illustrated. The cell populations were sorted by flow cytometry utilizing an antibody to the human CD98 extracellular domain. The expression levels of the cell populations (solid lines) are shown relative to IMCD cells transfected with vector only (dotted line)
