Flow cytometric analysis of TRAIL-R1 and TRAIL-R2 cell surface expression. Cell lines clearly expressing both TRAIL-R1 and TRAIL-R2 (a) or primarily TRAIL-R2 with low or absent expression of TRAIL-R1 (b) are shown. Cells were stained with specific monoclonal antibodies for either TRAIL-R1 or TRAIL-R2 as indicated in the figure (blue) or with isotype matched control antibodies (red), with each curve representing 10,000 counted cells.
