 CD4 Blood Control:

 

The enumeration of CD4+ T cells in human blood by flow cytometry provides a vital tool when evaluating human immunodeficiencies.

Cytomark CD4 Blood Controls are controls designed to contain normal (CD4 Normal Blood Control) and low (CD4 Low Blood Control) levels of CD4+ T cells in whole blood, whilst maintaining a normal whole blood forward/side scatter profile on flow cytometry.

The CD4 Normal Blood Control contains CD4+ T cells in the normal range (410-1590 cells/µl) and the CD4 Low Blood Control contains CD4+ T cells in a low range (200-300 cells/µl). These controls can be purchased separately or as a pair.

The Blood Controls are intended as daily run controls to ensure that sample processing, equipment and operators are all performing optimally thereby providing quality assurance in immune monitoring of patients. They should be processed in the same manner as the patient samples.

Benefits of CD4 Blood Controls

  • Available in two formats, CD4 Low and CD4 Normal
  • Verification of monoclonal antibody and FACS reagents
  • Validation of flow cytometer performance
  • Validation of operator technique
  • Verification of red blood cell lysis
