Flow cytometric analysis of Granzyme C expression in activated Mouse splenic leucocytes. C57BL/6 mouse splenic leucocytes were activated by culture with Recombinant Mouse IL-15 protein (100 ng/ml) for 4 days (37°C). The cells were harvested, washed, preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142] then stained with BD Horizon™ BUV395 Mouse Anti-Mouse NK-1.1 antibody (Cat. No. 564144) and BD Horizon™ Fixable Viability Stain 510 (Cat. No. 564406). The cells were then fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and then washed and permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723) and stained with either PE Rat IgG1, κ Isotype Control (Cat. No. 553925; Left Plot) or PE Rat Anti-Mouse Granzyme C antibody (Cat. No. 568735; Right Plot) at 0.5 µg/test. The bivariate pseudocolor density plot showing the correlated expression of Granzyme C (or Ig Isotype control staining) versus NK-1.1 was derived from gated events with the forward and side light- scatter characteristics of viable (Fixable Viability Stain 510-negative) splenocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific

Preparation And Storage
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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
Companion Products
The SFC1D8.rMAb is a recombinant Rat IgG1 κ monoclonal antibody with VH and VL regions derived from SFC1D8 hybridoma cells that secrete Armenian Hamster IgG antibodies specific for Mouse Granzyme C. Granzyme C is also known as Cytotoxic cell protease 2 (CCP2) or Ctla5 (Ctla-5). Granzyme C is a serine protease that is encoded by Gzmc (granzyme C) which belongs to the peptidase S1 family. Granzyme C is found in the cytotoxic granules of cytotoxic T lymphocyte and natural killer (NK) effector cells. Upon recognition of target cells, these effector cells can exocytose Granzyme C which induces apoptosis of target cells leading to their externalization of phosphatidylserine, nuclear condensation, mitochondrial swelling, and the single-stranded DNA nicks. Granzyme C can reportedly support cytotoxic T lymphocyte-mediated killing of target cells in the absence of Granzyme A or B.
