      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 to the dye under optimum conditions that minimize unconjugated dye and antibody.

      推荐的实验流程

      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.

      1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      2. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
      3. For U.S. patents that may apply, see bd.com/patents.
      4. 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.
      5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      6. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
      7. 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.
      8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      9. An isotype control should be used at the same concentration as the antibody of interest.
      10. 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.
      11. 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.

      9B1

      The 9B1 monoclonal antibody specifically binds to CD199 which is also known as Chemokine (C-C motif) receptor 9 (CCR9) or C-C chemokine receptor type 9 (C-C CKR-9). CD199 is a ~42 kDa seven-transmembrane protein and member of the G protein-coupled receptor 1 family. CD199 binds to CCL25, which is likewise known as thymus-expressed chemokine (TECK) or small inducible chemokine 25 (Scya25). CCL25 is selectively and constitutively expressed in the thymic cortex and small intestinal epithelium. CD199 (CCR9) is highly expressed on CD4+CD8+ double-positive thymocytes and mature naïve CD8+ T cells, but not naïve CD4+ T cells, in the peripheral lymphoid organs. CD199 (CCR9) is also expressed on small intestinal B cells, and on subsets of memory CD4+ T cells and CD8+ T cells, and dendritic cells. The CCR9/CCL25 pathway plays important roles in T cell development and gut-associated immune functions. It is especially involved in the recruitment of CD8αα+ intraepithelial lymphocytes (IELs) and the homing of other lymphocytes to the gut. Dysregulation of this pathway is associated with inflammatory responses, such as inflammatory bowel disease (IBD) and celiac disease.

      RB670
      The BD Horizon RealBlue™ 670 (RB670) Dye is part of the BD® family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 492 nm and an emission maximum (Em Max) at 670 nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB670 can be used on both spectral and conventional cytometers and is designed to be primarily excited by the Blue laser (488-nm). For conventional instruments equipped with only a Blue laser (488-nm), RB670 can be used as an alternative to PE-Cy5 and we recommend using an optical filter centered near 670-nm (eg, a 670/30-nm bandpass filter). For conventional and spectral instruments equipped with both a Blue (488-nm) and Yellow-Green (561-nm) laser and appropriate detectors, it can be used in conjunction with PE-Cy5.
