DURAClone IM Dendritic Cells Protocol

This protocol is for reference purposes only.  It may be necessary to adapt the method for specific research needs.

Materials

KIT BOX CONTENTS

25 tests of the DURAClone IM Dendritic Cell Antibody Panel

3 Compensation Kits, each kit containing eight single color tubes:

  • CD4-FITC
  • CD4-PE
  • CD1c-PC5.5
  • CD11c-PC7
  • CD4-APC
  • CD123-APC-Alexa Fluor 700
  • CD4-Pacific Blue
  • CD8-Krome Orange

NOTE: Do not store the reagent tubes in the refrigerator; do not freeze/thaw the tubes. Minimize the exposure of the tubes to light, especially during processing and incubation of sample(s) prior to acquisition.

MATERIAL REQUIRED BUT NOT SUPPLIED

Staining Procedure

SAMPLE PREPARATION 

  1. Add 200 μL of whole blood to one tube of the DURAClone IM Dendritic Cells Antibody Panel.

  2. Vortex at high speed for 6-8 seconds and incubate for 15 minutes between 20 and 30 °C. Protect from light.

  3. Add 2 mL of VersaLyse, vortex at high speed for 1-3 seconds and incubate for 15 minutes between 20 - 30 °C. Protect from light.

  4. Centrifuge the tube at 200 x g for 5 minutes; aspirate the supernatant. Gently tap to dissociate the pellet.

  5. Add 3 mL 1X PBS; centrifuge at 200 x g for 5 minutes. Aspirate the supernatant. Gently tap to dissociate the pellet.

  6. Resuspend cells in 500 μL of 1X PBS/Fixative solution.

  7. The sample is ready for acquisition.

COMPENSATION SETUP

  1. Add 100 μL of whole blood to each of the single color tubes in the Compensation Kit.  All tubes should be from the same pouch.

  2. Add one drop of the positive VersaComp Antibody Capture Beads of the following compensation tubes:

    • CD1c-PC5.5
    • CD123-APC-Alexa Fluor 700

  3. Follow steps 2-7 in the Sample Preparation procedure.

  4. Follow standard procedures and instrument manufacturer instructions for compensation setup.
