Are most appropriate when you need reference/control cells for longitudinal, multi-center studies.


Reference laboratories, clinical research organizations, and multi-center clinical trials, among other institutions, need reliable controls to monitor assay performance and variability for longitudinal studies. Veri-Cells™ is our line of lyophilized control cell products, which can be used to help monitor data quality and aid in reproducibility in multi-center and longitudinal studies. 

Veri-Cells™ feature:

  • Exceptional long term stability
  • Scatter profile similar to fresh samples
  • Validation for the detection of over 150 markers

Veri-Cells™ Activated (Cytokine) PBMC

Veri-Cells™ Activated (Cytokine) PBMC have been activated with our Cell Activation Cocktail (with Brefeldin A), which includes phorbol 12-myristate 13-acetate (PMA) and Ionomycin, for 6 hours. They have been validated to stain for activation-induced cytokines including IL-2, IL-3, IL-4, IL-5, IL-8, IL-13, IL-17, GM-CSF, IFN-γ, and TNF-α, along with surface markers typically expressed on human PBMCs. Cells do not require additional fixation nor permeabilization prior to cytokine staining, thus saving more time in your experiment.




Veri-Cells™ Activated (Surface)

Veri-Cells™ Activated (Surface) have been activated with Concanavalin A for 72 hours. This makes them ideal for the detection of T cell activation markers, including CD25, CD69, CD134, CD279, CD366, and TIGIT.




Veri-Cells™ Phospho PBMC (MAPK/ERK Pathway)

Veri-Cells™ Phospho PBMC are stimulated with PMA/Ionomycin for 15 minutes. This product includes both stimulated and vehicle control cells for the staining of RAS mitogen-activated kinase pathways, including phospho-S6, phospho-p38, and phospho-ERK1/2.




Veri-Cells™ CD34 PBMC

Veri-Cells™ CD34 PBMC contains mixture of CD34+ KG-1a cells and human PBMCs to help verify CD34 antibody binding without the need for artificial enrichment or the collection of a large number of events.




Veri-Cells™ Leukocytes 

Unlike Veri-Cells™ PBMC and CD4-Low PBMC, Veri-Cells™ Leukocytes contain neutrophils and eosinophil populations. These cells can be used as controls or reference material to monitor expression of granulocyte markers such as CD15 and CD16.




Veri-Cells™ CD4-Low PBMC

Veri-Cells™ CD4-Low PBMC are specially formulated to contain a lower frequency of CD4+ cells, similar to that observed in patients with CD4 immunodeficiency. The expected frequency of CD3+ CD4+ cells can be found on the certificate of analysis for that lot.




Veri-Cells™ PBMC

Veri-Cells™ PBMC consist of lyophilized human PBMCs validated for over 150 surface markers and intracellular targets and exhibit a scatter profile similar to freshly isolated cells. Please refer to the Validation Tab to view the full listing of markers and clones that can be used with Veri-Cells™ PBMC.
