Flow cytometric analysis of CD68 expression by Human peripheral blood monocytes. Human peripheral blood mononuclear cells were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655). After washing with BD Perm/Wash™ Buffer (Cat. No. 554723), the cells were stained in BD Perm/Wash™ Buffer with either BD Horizon™ RB705 Mouse IgG2b, κ Isotype Control (Cat. No. 570273; dashed line histogram) or BD Horizon™ RB705 Mouse Anti-Human CD68 antibody (Cat. No. 570646/570732; solid line histogram). The fluorescence histogram showing CD68 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of intact monocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Flow cytometric analysis of CD68 expression by Human peripheral blood mononuclear cells. Human peripheral blood mononuclear cells (PBMC) were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655). After washing with BD Perm/Wash™ Buffer (Cat. No. 554723), the cells were stained in BD Perm/Wash™ Buffer with either BD Horizon™ RB705 Mouse IgG2b, κ Isotype Control (Cat. No. 570273; Left Plot) or BD Horizon™ RB705 Mouse Anti-Human CD68 antibody (Cat. No. 570646/570732; Right Plot). The bivariate pseudocolor density plot showing the correlated expression of CD68 (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals was derived from gated events with the forward and side light-scatter characteristics of viable leukocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Preparation And Storage

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. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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

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.
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.
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
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.
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.

Tandem fluorochromes contain both an energy donor and an energy acceptor. Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from the donor may be observed. Additionally, multi-laser cytometers may directly excite both the donor and acceptor fluorochromes. Therefore, we recommend for every tandem conjugate, a matched individual single-stain control be acquired for generating a compensation or spectral unmixing matrix.

Antibody Details

Y1/82A

The Y1/82A monoclonal antibody specifically binds to CD68 which is also known as, Scavenger receptor class D member 1 (SCARD1), Macrosialin, or GP110. CD68 is a cell surface 110 kDa-type I-transmembrane glycoprotein that is primarily expressed in cytoplasmic granules of monocytes, macrophages, dendritic cells, granulocytes, myeloid progenitor cells and, reportedly, a subset of CD34-positive hemopoietic bone marrow progenitor cells. CD68 belongs to the sialomucin family and serves as a scavenger receptor that can bind and internalize oxidized low density lipoproteins (LDL). This antibody is useful in studies of myeloid cell development and function.

Format Details

RB705

The BD Horizon RealBlue™ 705 (RB705) 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 707-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB705 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), RB705 can be used as an alternative to PerCP-Cy5.5 or BB700 and we recommend using an optical filter centered near 710-nm (e.g., a 695/40 or 710/50-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PerCP-Cy5.5. RB705 is on average brighter than PerCP-Cy5.5 and BB700, and has minimal spillover into Yellow-Green detectors.
