RY586 Mouse Anti-Human Granzyme B
RY586 Mouse Anti-Human Granzyme B
Two-color flow cytometric analysis of Granzyme B expression in peripheral blood lymphocytes. Human peripheral blood mononuclear cells (PBMC) were 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 FITC Mouse Anti-Human CD8 antibody (Cat. No.​ 555366/557085/561947/561948) and with either BD Horizon™ RY586 Mouse IgG1 Isotype Control (Cat. No. 568097; Left Plot) or BD Horizon™ RY586 Mouse Anti-Human Granzyme B antibody (Cat. No. 568133/568134; Right Plot). The bivariate pseudocolor density plot showing the correlated expression of Granzyme B (or Ig Isotype control staining) versus CD8 was derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis were performed using a BD FACSymphony™ A5 Cell Analyzer System and FlowJo™ Software.​

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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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.
  3. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  4. An isotype control should be used at the same concentration as the antibody of interest.

  7. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

GB11

The GB11 antibody specifically reacts with human granzyme B, a serine protease of  approximately 32 kDa.  Granzyme B is stored in the granules of cytotoxic T lymphocytes and NK cells along with the pore-forming protein perforin. In the classic model of target cell lysis, perforins create holes in the target cell membrane allowing entrance of granzymes.  Granzyme B has been shown to act on specific substrates including caspase-3, -7, -9, and -10 which in turn give rise to enzymes that mediate apoptosis. Granzyme B may also be involved in the hydrolysis of extracellular matrix components.  Detectable levels of granzyme B have been detected in sera from healthy volunteers. The immunogen used to generate the GB11 hybridoma was human granzyme B isolated from an NK cell line.

The BD Horizon RealYellow™ 586 (RY586) Dye is part of the BD family of yellow-green dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 565-nm and an emission maximum (Em Max) at 586-nm. Driven by BD innovation, RY586 can be used on both spectral and conventional cytometers and is designed to be excited by the Yellow-Green laser (561-nm) with minimal excitation by the 488-nm Blue laser. For conventional instruments equipped with a Yellow-Green laser (561-nm), RY586 can be used as an alternative to PE and we recommend using an optical filter centered near 586-nm (eg, a 586/15-nm bandpass filter). For spectral instruments equipped with a Yellow-Green laser (561-nm), it can be used in conjunction with PE. Compared to PE, RY586 is similar in brightness, minimal spillover into Blue detectors, and increased spillover into the 610/20-nm (PE-CF594) detector. Please ensure that your instrument configuration (lasers and optical filters) is appropriate for this dye.
