The reconstituted lyophilized human PBMC can be used for immunofluorescent staining and multi-color flow cytometry assays. The cells can be used as controls for stability studies to avoid donor variability. View 150 markers verified by LEGENDScreen™.

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 HTLV (Human T-Lymphotrophic virus I and II), surface antigen for Hepatitis B (HBsAg) virus and syphilis and 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.

ICFC - Verified

Recommended Usage

50 µl per test (after reconstitution with 1.3 ml)

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

Application Notes

The Veri-Cells™ CD4-Low PBMC Kit can be used as positive controls for surface and intracellular immunofluorescent staining and multi-color flow cytometry assays. Assay values for CD3+CD4+ cells will be provided for each lot produced. It can also be used for the detection of intracellular molecules such as Granzyme B, Perforin, Foxp3 and Helios using BioLegend’s Fixation Buffer (Cat. No. 420801) and Intracellular Staining Permeabilization Wash Buffer (10X) (Cat. No. 421002) or the True Nuclear™ Transcription Factor Buffer Set (Cat. No. 424401). For best results, Cell Staining Buffer (Cat. No. 420201) is recommended for any washing steps. Please note, any claims relative to product performance are based on testing with BioLegend reagents and protocols. Deviations from the use of these reagents and procedures have not been assessed and may affect performance.


Please use our CoA Look-Up Tool to find the expected lot-specific frequencies of certain cell populations included within each lot of Veri-Cells™ CD4-Low PBMC. The antibodies used for testing were the following: CD3 FITC (clone UCHT1) and CD4 PE/Cy7 (clone RPA-T4).  Percent positive is based on gates set on unstained cells. The Certificate of Analysis specific values are provided only as a reference. Variability in antibodies used, instruments, staining conditions and other factors may influence end-user values. It is recommended that individual laboratories establish its own control values and ranges for each parameter based on laboratory specific conditions and protocols.
