Stabilised Human Whole Blood

Quantitation of leucocytes in human whole blood by flow cytometry provides a vital tool in evaluating many human immunodeficiencies.

Stabilised Human Whole Blood Control and CD4 Low and Normal Blood Controls developed by Cytomark are stabilised preparations of human whole blood for use in research applications. They are commonly used for flow cytometric analysis to ensure that sample processing, equipment and operators are all performing optimally, thereby providing quality assurance.

Stabilised Human Whole Blood Control and CD4 Low and Normal Blood should be processed in the same manner as fresh or TransFix stabilised blood samples.

Key benefits include:

  • Verification of monoclonal antibodies and flow cytometry reagents
  • Validation of flow cytometer performance
  • Validation of operator technique
  • Verification of red blood cell lysis
