BD Horizon™ RY743 Rat Anti-Mouse IFN-γ
Clone XMG1.2 (RUO)
Two-color flow cytometric analysis of IFN-γ expression in stimulated Mouse splenic leukocytes. BALB/c Mouse splenocytes were stimulated for 5 hours with Phorbol 12-Myristate 13-Acetate (PMA; Sigma P-8139; 50 ng/ml) and Ionomycin (Sigma I-0634; 1 μg/ml) in the presence of BD GolgiStop™ Protein Transport Inhibitor (containing Monensin) [Cat. No. 554724]. The cells were harvested and washed with BD Pharmingen™ Stain Buffer (FBS) [Cat. No. 554656] and fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655). The cells were then washed and stained in BD Perm/Wash™ Buffer (Cat. No. 554723) with BD Horizon™ BUV395 Rat Anti-Mouse CD4 antibody (Cat. No. 568375) and with either BD Horizon™ RY743 Rat IgG1, κ Isotype Control (Cat. No. 572232; Left Plot) or BD Horizon™ RY743 Rat Anti-Mouse IFN-γ antibody (Cat. No. 572230/572231; Right Plot) at 0.125 µg/test using BD Biosciences Intracellular Cytokine Staining protocol. The bivariate pseudocolor density plot showing the correlated expression of IFN-γ (or Ig Isotype control staining) versus CD4 was derived from gated events with the forward and side light-scatter characteristics of intact stimulated leukocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ Software. Data shown on this Technical Data Sheet are not lot specific.

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 and unreacted dye was removed. 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
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- 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.
- 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.

Antibody Details
XMG1.2
The XMG1.2 monoclonal antibody specifically binds to mouse interferon-γ (IFN-γ) protein. IFN-γ is a pleiotropic cytokine, of approximately 15-17 kDa, involved in the regulation of inflammatory and immune responses. It plays an important role in activation, growth, and differentiation of T and B lymphocytes, macrophages, NK cells and other non-hematopoietic cell types. IFN-γ production is associated with the Th1 cell differentiation. The purified form of this antibody has been reported to be a neutralizing antibody.

Format Details
RY743
The BD Horizon RealYellow™ 743 (RY743) Dye is part of the BD® family of yellow-green dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 557 nm and an emission maximum (Em Max) at 743 nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RY743 is optimized for detection on spectral cytometers and designed to be excited by the Yellow-Green laser (561 nm) with minimal excitation by the Blue laser (488 nm). Given its unique emission max, RY743 can be used on a spectral instrument in combination with RY703 and either RY775 or PE-Cy7 to provide an additional color excited by the Yellow-Green laser. For conventional instruments equipped with a Yellow-Green laser, we recommend using an optical filter centered near 750 nm (e.g., a 750/60-nm bandpass filter). Please ensure that your instrument configuration (lasers and optical filters) is appropriate for this dye.
