CST, 4084S, DRAQ5 ®

Product Usage Information
Please follow CST's recommended IF and Flow protocols. For both applications, following secondary detection: Flow Cytometry: Centrifuge cells and resuspend in 0.5 ml DRAQ5 ® diluted 1:500 (10 µM) in PBS or Antibody Dilution Buffer. Incubate for 5 min at room temperature in the dark before analyzing cells on flow cytometer. Immunofluorescence: Rinse samples twice in PBS for five minutes each. Dilute DRAQ5 ® 1:1000 (5 µM) in PBS and incubate for 5 minutes at room temperature in the dark. Rinse samples once in PBS, coat coverslips with anti-fade reagent and examine immediately using appropriate excitation wavelength.
Storage
Store at 4°C protected from light.
