(RUO)

Multiparameter flow cytometric analysis of CD215 (IL15Rα) expression on human monocytes. Human peripheral blood mononuclear cells were cultured in complete tissue culture medium without (Left Plots) or with (Right Plots) lipopolysaccharide (LPS, 100 ng/ml) and Recombinant Human IFN-γ protein (Cat. No. 554617, 10 ng/ml) for 20 hours at 37°C. The cells were harvested, preincubated with Human BD Fc Block™ (Cat. No. 564219), and then stained with BD Horizon™ BV421 Mouse Anti-Human CD14 antibody (Cat. No. 565283) and with either APC Mouse IgG2b, κ Isotype Control (Cat. No. 565381; Upper Plots) or APC Mouse Anti-Human CD215 (IL15Rα) antibody (Cat. No. 567740/567741; Lower Plots). BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. Bivariate pseudocolor density plots showing the correlated expression of CD215 (IL15Rα) [or Ig Isotype control staining] versus CD14 were derived from gated events with the forward and side light-scatter characteristics of viable (7-AAD-negative) monocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cell and CompBead to ensure that BD® CompBeads are appropriate for your specific cellular application.

Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.

An isotype control should be used at the same concentration as the antibody of interest.

JM7A4

The JM7A4 monoclonal antibody specifically binds to CD215, which is also known as the IL-15 Receptor alpha subunit (IL-15R-alpha, IL-15Ra, or IL-15Rα). This type I transmembrane glycoprotein is encoded by IL15RA (Interleukin 15 receptor subunit alpha) and is variably expressed on macrophages, natural killer (NK) cells, T cells and B cells and by some nonlymphoid cells including fibroblasts. Although it can independently bind IL-15 with high affinity, it does not contain a signaling motif. CD215 (IL-15Rα) can present IL-15 in cis or trans fashion to the IL-2/15R beta (CD122) and IL-2R gamma (γc or CD132) receptor complex which can then transduce signals intracellularly. Several different CD215 (IL-15Rα) isoforms have been described that are produced by alternative splicing and may alter signal transduction responses to IL-15. A cleaved soluble form of CD215 known as sIL-15RA has also been reported which can bind and antagonize IL-15 activity. By binding to its heterotrimeric receptor, IL-15 plays crucial roles in innate immunity, eg, through the activation of NK cells and adaptive immunity, eg, in enhancing the survival of CD8+ memory T cells.

Format Details

APC

Allophycocyanin (APC), is part of the BD family of phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 651 nm and an emission maximum (Em Max) at 660 nm. APC is designed to be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 660 nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: APC

Excitation Source: Red 627-640 nm

Excitation Max: 651 nm

Emission Max: 660 nm
