      PerCP-Cy™5.5 Rat Anti-CD11b
      Flow cytometric analysis of CD11b expression on mouse bone-marrow myeloid cells.  BALB/c bone-marrow leukocytes were stained with either Purified Rat IgG2b, κ Isotype Control (Cat. No. 553986; left panel) or Purified Rat Anti-Mouse CD11b antibody (Cat. No. 553308/550282/557394; right panel), followed by FITC Goat Anti-Rat Ig (Cat. No. 553308). Please note that the population of cells having the lowest SSC (erythroid and lymphoid cells) show little expression of CD11b, while cells with moderate-to-high SSC (myeloid cells) are almost uniformly CD11b positive (right panel). The contour plots showing CD11b expression (or Ig Isotype control staining) were derived from gated events with the forward and side light-scatter characteristics of myeloid cells (ie, moderate-to-high side light-scatter-gated events). Flow cytometry was performed on a BD FACScan™ flow cytometry system.

      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 with PerCP-Cy5.5 under optimum conditions, and unconjugated antibody and free PerCP-Cy5.5 were removed. Storage of PerCP-Cy5.5 conjugates in unoptimized diluent is not recommended and may result in loss of signal intensity.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. An isotype control should be used at the same concentration as the antibody of interest.
      3. 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.
      4. PerCP-Cy5.5–labelled antibodies can be used with FITC- and R-PE–labelled reagents in single-laser flow cytometers with no significant spectral overlap of PerCP-Cy5.5, FITC, and R-PE fluorescence.
      5. PerCP-Cy5.5 is optimized for use with a single argon ion laser emitting 488-nm light. Because of the broad absorption spectrum of the tandem fluorochrome, extra care must be taken when using dual-laser cytometers, which may directly excite both PerCP and Cy5.5™. We recommend the use of cross-beam compensation during data acquisition or software compensation during data analysis.
      6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      7. 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.
      8. Cy is a trademark of GE Healthcare.
      9. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
      10. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

      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.

      PerCP-Cy5.5
      PerCP-Cy5.5 dye is part of the BD blue family of dyes. This tandem fluorochrome is comprised of a fluorescent protein complex (PerCP) with an excitation maximum (Ex Max) of 482 nm and an acceptor dye with an emission maximum (Em Max) at 676 nm. PerCP-Cy5 is designed to be excited by the blue laser (488-nm) and detected using an optical filter centered near 680 nm (e.g., a 695/40 nm bandpass filter). The donor dye can be partially 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.
