Description

The Human GPI-APD Cocktail for WBC with Control Cells kit is a ready-to-use solution for high-sensitivity identification of glycosylphosphatidylinositol (GPI)-deficient populations that are characteristic of paroxysmal nocturnal hemoglobinuria (PNH) and related disorders.

The kit includes a liquid antibody cocktail that is designed in accordance with ICCS recommendations and is optimized to detect GPI-anchored proteins on neutrophils and monocytes, including CD24, CD14, and CD157.  It also incorporates fluorescent labelled aerolysin (FLAER), a reagent that selectively binds to cell surface GPI-anchored proteins.

The Veri-Cells™ control provides a standardized quality control system, ensuring reliable assay validation for PNH and other GPI-deficiencies.  This unique component contains stabilized cells with detectable and undetectable GPI-anchored markers.

This product contains human cells, a potentially biohazardous material. Blood used in preparation of these samples was tested and found to be negative, using FDA-approved methods for antibody and nucleic acid testing against Human Immunodeficiency virus (HIV), Hepatitis B and C virus, and HTL Human T-Lymphotropic virus I and II (HTLV), surface antigen for Hepatitis B (HBsAg) virus, syphilis, and the West Nile Virus. Biological tests are not 100% accurate.

Use standard precautions when handling and treat as if the product is capable of transmitting disease. When handling or disposing, follow precautions described in CDC and FDA recommendations and OSHA Bloodborne Pathogen guidelines.

Storage & Handling
Store the kit at 2°C - 8°C upon receipt. Do not open sealed pouch until ready to use. Unstained Veri-Cells™ Leukocytes reconstituted in Buffer A Plus or GPI Buffer can be stored separately up to five days at 2°C - 8°C. Do not mix the two reconstituted Veri-Cells™ Leukocytes until ready to use as Veri-Cells™ Control Cells.
Application

FC - Quality tested
Recommended Usage

Veri-Cells™ Leukocytes: 50 μL per test (after reconstitution with 325 μL of Veri-Cells™ Buffer A Plus or GPI Buffer). Once reconstituted, let the cells sit for at least 30 minutes at room temperature prior to staining.

GPI-APD cocktail for WBC: the suggested use of this reagent is 20 μL per 50 μL reconstituted Veri-Cells™ or 100 μL of whole blood for flow cytometric staining. It is recommended that the reagent be titrated for optimal performance for each application.

Note: Veri-Cells™ Buffer A plus and GPI Buffer may show precipitation over time; however, this is normal and does not affect the performance of the buffer.

Application Notes

Veri-Cells™ Control Cell Protocol

  1. Remove the kit from the fridge and allow it to warm to room temperature for 5 minutes. Keep unused kit components stored in the fridge.
  2. Reconstitute 1 Veri-Cells™ Leukocytes vial with 325 µL of Buffer A Plus. Reconstitute a second Veri-Cells™ Leukocytes vial with 325 µL of GPI Buffer. Label each vial with the reconstitution buffer (“Buffer A Plus” and “GPI Buffer”)
  3. Incubate the 2 vials at room temperature for 30 minutes.
  4. Prepare two 5 mL FACS tubes (not provided). Label one “Buffer A Plus” and the other “GPI Buffer.”
  5. Add 20 μL of the GPI-APD Cocktail for WBC to each tube
  6. Add 50 μL of Veri-Cells™ Leukocytes reconstituted in Buffer A Plus or GPI Buffer to the appropriately labeled tube. 
  7. Incubate the cells at room temperature and in the dark for about 15 minutes.
  8. Add 2 mL of Cell Staining Buffer (Cat. No. 420201). 
  9. Centrifuge at 350 x g for five minutes. Discard supernatant.
  10. Wash one more time with 2 mL of Cell Staining Buffer.
  11. Resuspend cell pellet in 0.2 - 0.4 mL of Cell Staining Buffer.
  12. Combine the two tubes to make one tube of “Veri-Cells™ Control Cells.”
  13. Acquire cells immediately (along with samples) on a flow cytometer or store at 4°C, in the dark, for no longer than 12 hours. 

​Note: Unstained Veri-Cells™ Leukocytes reconstituted in Buffer A Plus or GPI Buffer can be stored separately up to five days at 2°C - 8°C.

Whole Blood Cell (WBC) Protocol

  1. Prepare 1X RBC Lysis/Fixation solution by diluting 1 part of RBC Lysis/Fixation solution with 9 parts of room temperature deionized water. 
  2. Prepare single color controls (listed in the Recommended Reagents) using either WBC or Compensation Beads (Cat. No. 424602).
  3. Mix 100 μL of whole blood with 20 μL of the GPI-APD Cocktail for WBC.
  4. Incubate at room temperature, in the dark, for 15 minutes. 
  5. Add 2.0 mL of 1X RBC Lysis/Fixation solution, gently mixing each tube immediately.
  6. Incubate at room temperature, in the dark, for 15 minutes.
  7. Centrifuge at 350 x g for five minutes. Discard supernatant.
  8. Add 2 mL of Cell Staining Buffer.
  9. Centrifuge at 350 x g for five minutes. Discard supernatant.
  10. Wash one more time with 2 mL of Cell Staining Buffer.
  11. Resuspend cell pellet in 0.3 - 0.5 mL of Cell Staining Buffer.
  12. Acquire cells immediately (along with Veri-Cells™ Control Cells) on a flow cytometer or store at 4°C, in the dark, for no longer than 12 hours.
