CD4 Low and Normal Blood Controls
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
CD4 Low and Normal Blood Controls (RUO)
Cytomark CD4 Blood Controls are stabilised whole blood 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.
|CF04-L||CD4 Low Blood Control||1.5ml|
|CF04-N||CD4 Normal Blood Control||1.5ml|
|CF04-Duo||CD4 Low and Normal Blood Control Set||2×1.5ml|
CD4 Blood Controls can be used in External Quality Assurance (EQA) programmes due to their exceptional stability. Human source material used to manufacture these products is tested for all known UK and European required communicable disease agents using UK NEQAS approved testing methods.
