RB780 Rat Anti-Mouse Ly-6C
RB780 Rat Anti-Mouse Ly-6C
Two-color flow cytometric analysis of Ly-6C expression on Mouse splenocytes. BALB/c Mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with BD Horizon™ BV421 Rat Anti-Mouse CD8a antibody (Cat. No. 563898) and with either BD Horizon™ RB780 Rat IgM, κ Isotype Control (Cat. No. 568742; Left Plot) or BD Horizon™ RB780 Rat Anti-Mouse Ly-6C antibody (Cat. No. 568738/568739; Right Plot) at 0.5 μg/test. The bivariate pseudocolor density plot showing the correlated expression of Ly-6C (or Ig Isotype control staining) versus CD8a was derived from gated events with the forward and side light-scatter characteristics of viable splenic leucocytes. Flow cytometry and data analysis were performed using BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

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 to the dye under optimum conditions and unreacted dye was removed.

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

AL-21

The AL-21 monoclonal antibody specifically binds to a non-polymorphic determinant of Ly-6C, a 14-17 kDa GPI-linked cell-surface antigen found on some monocyte/macrophage populations, granulocytes, endothelial cells, plasma cells, and thymocyte, NK-cell, and T-subsets.  Mice with the Ly-6.2 alloantigen (eg, AKR, C57BL, C57BR, C57L, C58, DBA/2, PL, SJL, SWR, 129) have subsets of CD8+ and CD4+ Ly-6C+ T cells, while Ly-6.1 strains (eg, A, BALB/c, CBA, C3H/He, DBA/1, NZB) have only CD8+ Ly-6C+ T cells.   Upregulation of Ly-6C expression on CD8+ T cells by interferons α and β and poly (I:C) has been described,  and Ly-6C is a memory marker on CD8+ T cells.

RB780
The BD Horizon RealBlue™ 780 (RB780) 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 781-nm. Driven by BD innovation, RB780 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), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors.
