Here are a few examples where DRAQ5 and DRAQ7 have been used on Miltenyi Biotec's MACSQuant flow cytometers:
DRAQ7 - for dead cell exclusion
McKimmie et al., Blood 2013

Surface expression assay for EGFR & cMET comparing 2D and 3D cultured NSCLC: PE-labeled anti-HGF/cMET and anti-EGFR antibodies, PE quantification beads and DRAQ7 to exclude dead cells.
DRAQ5 - for cell cycle analysis
Canham et al., PloS One 2014
http://dx.doi.org/10.1371/journal.pone.0115379
Cell cycle analysis assay in pre-neoplastic cervical disease: PE-labeled TRA-1-60 cell surface stem cell marker and DRAQ5 were combined to analyse cell cycle dynamics in cancer stem cell-like populations relative to neoplasia grading.
