      PE Rat Anti-Mouse CD93 (Early B Lineage)
      PE Rat Anti-Mouse CD93 (Early B Lineage)
      The expression of CD93 (Early B Lineage) antigen on developing and peripheral B lymphocytes. BALB/c bone marrow cells (top panels) and splenocytes (bottom panels) were stained with FITC Rat Anti-Mouse CD45R/B220 (Cat. No. 553087) and either PE Rat IgG2b, κ Isotype Control (Cat. No. 553989; left panels) or PE Rat Anti-Mouse CD93 (Early B Lineage) (Cat. No. 558039; right panels). Viable cells were selected by exclusion of propidium iodide, and flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.

      准备和存储

      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 R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

      推荐的实验流程

      For detection of the Early B Lineage antigen in the spleen, we recommend amplification of the staining signal through the use of Biotin Rat Anti-Mouse CD93 (Early B Lineage) (Cat. No. 550434), followed by a "bright" second-step reagent, such as Streptavidin-PE (Cat. No. 554061).

      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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      5. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

      AA4.1

      The AA4.1 monoclonal antibody specifically recognizes the Early B Lineage antigen which is also known as CD93, AA4 antigen, Ly-68, and Complement component C1q receptor (C1qRp). This 130-140-kDa type I transmembrane glycoprotein is expressed on immature B lymphocytes in the adult bone marrow and on  hematopoietic progenitors and stem cells in adult bone marrow, fetal liver, and embryonic yolk sac. Although CD93+ cells are most plentiful in adult mouse bone marrow, a smaller number of CD93+ cells which express lower CD93 levels can be detected in the adult spleen using bright fluorescent conjugates of the AA4.1 antibody or an amplified indirect immunofluorescent staining procedure. It has been observed that the staining pattern of the 493 monoclonal antibody is similar to that of the AA4.1 antibody, in that both antibodies precipitate molecules of the same molecular weight. Staining with the AA4.1 antibody is not blocked by the 493 antibody. These results suggest that the antibodies recognize separate epitopes on the same Early B Lineage antigen.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
