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 that minimize unconjugated dye and antibody. 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

  1. 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.
  2. 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.
  3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  4. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  5. An isotype control should be used at the same concentration as the antibody of interest.
  6. 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.
  7. 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.

30-F1

The 30-F1 monoclonal antibody specifically recognizes CD24 which is also known as Heat-Stable Antigen (HSA or HsAg). CD24 is a highly glycosylated sialoprotein that is glycosylphosphatidylinositol (GPI)-linked to the cell membrane. CD24 is encoded by Cd24a (CD24a antigen) and is variably expressed on thymocytes, lymphocytes, monocytes, granulocytes, and erythrocytes. Hematopoietic stem cells of the embryonic yolk sac and fetal liver express CD24. The expressed levels of CD24 vary during the developmental stages of cells within the T and B cell lineages. In the bone marrow, hematopoietic progenitors acquire CD24 expression upon commitment to the lymphocyte lineage. Immature B cells in the bone marrow and spleen of adult mice express high levels of CD24, whereas mature peripheral B cells express intermediate levels of CD24. The majority of thymocytes express high levels of CD24, whereas mature thymic and peripheral T cells do not express CD24. In contrast, γδ TCR-bearing thymocytes which emigrate to the spleen are CD24+. Dendritic cells of the thymus, spleen, and liver and epidermal Langerhans cells reportedly express CD24 whereas NK cells and plasma cells do not. CD24 can function as an adhesion molecule and serve as a ligand for CD62P (P-selectin). It can be involved in the costimulation of CD4+ T cells by B cells as well as function as a "co-inducer" of in vitro thymocyte maturation. 30-F1 and other CD24-specific monoclonal antibodies, such as, M1/69 and J11d, can show subtle differences in the staining patterns for different lymphocyte populations. For this reason, the consistent use of the same CD24-specific antibody is recommended during research studies.

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.
