Flow Cytometry General Protocol

A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. 20X Phosphate Buffered Saline (PBS): (#9808) To prepare 1 L 1X PBS: add 50 ml 20X PBS to 950 ml dH2O, mix.
  2. 16% Formaldehyde (methanol free).
  3. 0.1% Saponin in 1X PBS.
  4. Incubation Buffer: Dissolve 0.5 g Bovine Serum Albumin (BSA) (#9998) in 100 ml 1X PBS. Store at 4°C.
  5. Recommended Anti-Rabbit secondary antibodies:

B. Fixation

  1. Collect cells by centrifugation and aspirate supernatant.
  2. Resuspend cells in 0.5–1 ml 1X PBS. Add appropriate volume of 16% Formaldehyde to obtain a final concentration of 4% (e.g. 750 μl PBS + 250 μl 16% Formaldehyde).
  3. Fix for 10 min in a 37°C water bath.
  4. Chill samples on ice for 1 min.
  5. For extracellular staining with antibodies that do not require permeabilization, proceed to immunostaining (Section D) or store cells in 1X PBS with 0.1% sodium azide at 4°C; for intracellular staining, proceed to permeabilization (Section C).

C. Permeabilization

  1. Wash cells by centrifugation and resuspend in 1 ml 0.1% Saponin/1X PBS.
  2. Incubate 30 min at room temperature.
  3. Add 2 ml of 0.1% Saponin/1X PBS and wash by centrifugation.

D. Immunostaining

  1. Resuspend cells in 100 µl of primary antibody diluted in 0.1% Saponin/1X PBS. See individual antibody datasheet or product webpage for the appropriate antibody dilution.
  2. Incubate for 1 hr at room temperature.
  3. Wash by centrifugation in 2 ml 0.1% Saponin/1X PBS.
  4. Resuspend cells in fluorochrome-conjugated secondary antibody or fluorochrome-conjugated avidin, diluted in 0.1% Saponin/1X PBS at the recommended dilution.
  5. Incubate for 30 min at room temperature.
  6. Wash by centrifugation in 2 ml 0.1% Saponin/1X PBS.
  7. Resuspend cells in 0.5 ml 1X PBS and analyze on flow cytometer; alternatively, for DNA staining, proceed to optional DNA dye (Section E).

E. Optional DNA Dye

  1. Resuspend cells in 0.5 ml of DNA dye (e.g. Propidium Iodide (PI)/RNase Staining Solution #4087).
  2. Incubate for at least 30 min at room temperature.
  3. Analyze cells in DNA staining solution on flow cytometer.

Specificity / Sensitivity

IL-17A (D1X7L) Rabbit mAb (Mouse Specific) (PE Conjugate) recognizes endogenous levels of total mouse IL-17A protein.


Species Reactivity: Mouse
Species predicted to react based on 100% sequence homology: Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val49 of mouse IL-17A protein.

Product Description

This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometry analysis in mouse cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated IL-17A (D1X7L) Rabbit mAb (Mouse Specific) #13838.


The IL-17 family of cytokines consists of IL-17A-F, and their receptors include IL-17RA-RE (1). IL-17 cytokines are produced by a variety of cell types including the Th17 subset of CD4+ T cells, as well as subsets of γδ T cells, NK cells, and NKT cells (2). IL-17A and IL-17F, the most well-studied of the IL-17 cytokines, contribute to fungal and bacterial immunity by inducing expression of proinflammatory cytokines, chemokines, and antimicrobial peptides (2). In addition, IL-17A contributes to the pathogenesis of several autoimmune diseases (3). IL-17E promotes Th2 cell responses (4). The roles of IL-17B, IL-17C, and IL-17D are less clear, however these family members also appear to have the capacity to induce proinflammatory cytokines (1,5,6). IL-17 receptors have an extracellular domain, a transmembrane domain, and a SEFIR domain. They are believed to signal as homodimers, heterodimers, or multimers through their SEFIR domain by recruiting the SEFIR domain-containing adaptor Act1 (7). Unlike most cytokines that signal through Jak/STAT pathways, IL-17 signaling results in NF-κB activation (8).
