Multicolor flow cytometric analysis of CCR7 (CD197) on Human peripheral blood leucocytes and lymphocytes. Human whole blood was stained with APC Mouse Anti-Human CD4 (Cat. No. 561841), BD Horizon™ BUV395 Mouse Anti-Human CD8 (Cat. No. 563795/563796), BD Horizon™ BV421 Mouse Anti-Human CD45RA (Cat. No. 562885) antibodies, and with either BD Horizon™ RB780 Mouse IgG1, κ Isotype Control (Cat. No. 568532) or BD Horizon™ RB780 Mouse Anti-Human CCR7 (CD197) antibody [Cat. No. 568748/568749]. The erythrocytes were lysed with BD PharmLyse™ Lysing Buffer (Cat. No. 555899). Flow cytometry and data analysis were performed using a BD FACS LSRFortessa™ Flow Cytometer and FlowJo™ software. Plots 1 and 2: The bivariate pseudocolor density plots showing the correlated expression of CCR7 (CD197) [or Isotype control staining] versus side light-scatter (SSC-A) signals were derived from gated events with the forward and side light-scatter characteristics of viable leucocytes. Plot 3: The two-parameter pseudocolor density plot showing the correlated expression of CCR7 (CD197) versus CD45RA was derived from CD4-positive T cell gated events with the forward and side light-scatter characteristics of viable lymphocytes. Please note that we have observed considerable donor-to-donor variation in the proportion of CCR7 (CD197)-negative CD4-positive lymphocytes. Plot 4: The two-parameter pseudocolor density plot showing CCR7 (CD197) staining versus CD45RA was derived from CD8-positive T cell gated events with the forward and side light-scatter characteristics of viable lymphocytes.

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 unreacted dye was removed.
Recommended Assay Procedures
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® 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 cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Product Notices
- When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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).
- An isotype control should be used at the same concentration as the antibody of interest.
- Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

Antibody Details
2-L1-A
The 2-L1-A monoclonal antibody specifically binds to the human CC chemokine receptor CCR7, also known as CD197, on the cell surface. CCR7 (previously known as BLR2, EBI1 and CMKBR7) is a seven-transmembrane, G-protein-coupled receptor specific for two CC chemokines: CCL19 (also known as MIP-3β, Exodus-3, and ELC) and CCL21 (also known as 6Ckine, Exodus-2 SLC, TCA4, and SCYA21). CCR7 mRNA is expressed mainly in lymphoid tissues including the spleen, lymph nodes and tonsil, in bone marrow, and on peripheral T and B lymphocytes, cord blood CD34-positive cells, and mature dendritic cells. In response to its cognate chemokines, CCR7 (CD197) mediates homing of leucocytes to secondary lymphoid tissues. Differential CCR7 (CD197) expression can be used to distinguish naive, central memory, and effector memory T cell subsets. The human CCR7 gene, unlike other CC chemokine receptor genes, has been mapped to chromosome 17 (region 17q12). Because the extracellular region of CCR2 (CD192) has significant sequence homology with CCR7 (CD197), BD Biosciences has confirmed that mAb 2-L1-A does not cross-react with CCR2 on the surface of transfected cells.

Format Details
RB780
The BD Horizon RealBlue™ 780 (RB780) Dye is part of the BD family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 781-nm. Driven by BD innovation, RB780 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors.
