Multiparameter flow cytometric analysis of CD11b (Integrin αM) expression on Mouse bone marrow cells. BALB/c Mouse bone marrow cells were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with either BD Horizon™ BUV496 Rat IgG2b, κ Isotype Control (Cat. No. 612954; Left Plot) or BD Horizon™ BUV496 Rat Anti-CD11b (Integrin αM) antibody (Cat. No. 569708; Right Plot) at 0.25 µg/test. BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. The bivariate pseudocolor density plot showing the correlated expression of CD11b (Integrin αM) [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 (DAPI-negative) bone marrow cell populations. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ Software. Data shown on this Technical Data Sheet are not lot specific.

Multiparameter flow cytometric analysis of CD11b (Integrin αM) expression on Human peripheral blood leukocyte populations. Human whole blood was stained with either BD Horizon™ BUV496 Rat IgG2b, κ Isotype Control (Cat. No. 612954; Left Plot) or BD Horizon™ BUV496 Rat Anti-CD11b (Integrin αM) antibody (Cat. No. 569708; Right Plot) at 0.25 µg/test. Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The bivariate pseudocolor density plot showing the correlated expression of CD11b (Integrin αM) [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.

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 unconjugated antibody and free dye were 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.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

Note: When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed. For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).

Product Notices

Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
Since applications vary, each investigator should titrate the reagent to obtain optimal results.
An isotype control should be used at the same concentration as the antibody of interest.
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

M1/70

The M1/70 monoclonal antibody specifically binds to CD11b, also known as Integrin alpha M (Itgam or αM). CD11b is a 170-kDa type 1 transmembrane glycoprotein and belongs to the Integrin alpha chain family. CD11b serves as the alpha chain of the heterodimeric Mac-1 integrin (CD11b/CD18, αMβ2), also known as complement receptor 3 (CR3). Mac-1 mediates adhesion to ICAM-1 (CD54), ICAM-2 (CD102), fibrinogen and binding to C3bi. Mac-1 is expressed at varying levels on granulocytes, macrophages, myeloid-derived dendritic cells, natural killer cells, microglia, and B-1 B lymphocytes. Mac-1 expression is rapidly upregulated on neutrophils after activation, in the same time period that CD62L (L-selectin) is shed from the cell surface. The M1/70 antibody reportedly blocks cell adherence and C3bi binding but does not block cell-mediated lysis. Cross-reaction of the M1/70 antibody with CD11b expressed on human monocytes, polymorphonuclear leukocytes, and NK cells has been reported.

Format Details

BUV496

The BD Horizon Brilliant™ Ultraviolet 496 (BUV496) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This tandem fluorochrome is comprised of a BUV395 donor with an excitation maximum (Ex Max) of 350-nm and an acceptor dye with an emission maximum (Em Max) at 496-nm. BUV496, driven by BD innovation, is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 500-nm (e.g., 515/30-nm bandpass filter). The acceptor dye can be excited by the Violet (405-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: BUV496

Excitation Source: Ultraviolet 355 nm

Excitation Max: 350 nm

Emission Max: 496 nm
