BD Pharmingen™ HiCK-1 Human Cytokine Positive Control Cells
(RUO)
Preparation And Storage
After thawing and thoroughly resuspending cells with a pipette, "single-use" aliquots can be refrozen at -80°C and stored in polypropylene microtubes for use at a later time.
Recommended Assay Procedures
Flow Cytometry: HiCK-1 Cytokine Positive Control Cell suspensions contain intracellular IL-2, IFN-γ, and TNF which have accumulated and are detectable by intracellular flow cytometric analysis. These cells may serve as a positive control for verifying anti-cytokine antibody performance and/or the flow cytometric staining procedure itself (e.g. permeabilization). For flow cytometric staining, the frozen cell preparation should first be quickly and carefully thawed. Aliquots of the cell suspension can then be transferred to microwells or tubes. HiCK-1 cells are supplied fixed and non-permeabilized in dimethylsulfoxide (DMSO), so should be washed at least twice with staining buffer to remove the DMSO. The cells must then be permeabilized by incubating for 10-15 minutes in BD Perm/Wash™ buffer (Cat. No. 554723), spun down to pellet and then followed by at least one wash in BD Perm/Wash™ buffer. Cells can then be stained with either PE Rat Anti-Human IL-2 (Cat. No. 554566), PE Mouse Anti-Human IFN-γ (Cat. No. 554701), or PE Mouse Anti-Human TNF (Cat. No. 554513).
Note: Cytokine-specific antibody staining of HiCK-1 cells can be demonstrated by preincubation of conjugated cytokine-specific antibody with recombinant cytokine or by pretreatment of the HiCK-1 cells with unlabeled (purified) blocking antibody. Investigators should note that variation with cell activation may contribute to suboptimal blocking.

Companion Products
This suspension contains Human intracellular CytoKine-1 Positive Control Cells (HiCK-1). The HiCK-1 frozen cell suspension contains fixed, non-permeabilized human lymphoid cells. The suspension includes cells that express detectable levels of intracellular IL-2, IFN-γ and TNF as determined by immunofluorescent intracellular cytokine staining and flow cytometry. HiCK-1 cell suspensions were prepared by stimulating human PBMCs in the presence of a protein transport inhibitor. After stimulation, the cells were harvested and fixed, then stored in 1ml of 10% dimethylsulfoxide and 90% fetal bovine serum at -80°C. HiCK-1 cells contain a measurable proportion of cytokines, with representative flow cytometric data shown below. Performance from individual lots of HiCK-1 cells may differ due to donor variability. Investigators should anticipate similar, though not identical, results to those shown below.
