Description

Description: This human Th17 cytokine staining panel includes all reagents needed for simultaneous flow cytometric detection of all the major cytokines produced by the Th17 lineage: IL-17A, IL-17F, IL-21 and IL-22. An anti-CD4 antibody that can be used after fixation and permeabilization, as well as IC Fixation and Permeabilization Buffers, is also included.

CD4+ T helper cells are critical mediators of the cellular immune response. For many years, due to cytokine expression patterns, it was thought that CD4+ T helper cells existed as a dichotomy of lineages named Th1 and Th2. However, further investigation revealed that the T helper cell population was not limited to these two subsets. Although it had long been appreciated that IL-17 (also known as IL-17A) production by T cells was required for protection against some pathogens, studies demonstrated that this cytokine was produced by a unique subset of T helper cells. Subsequent reports definitively showed that T cells could differentiate into IL-17-producing cells in vitro and in vivo independent of Th1 or Th2 development, thereby establishing Th17 cells as a unique T helper cell lineage. In addition to IL-17A expression, Th17 cells have been reported to express IL-17F (an heterodimers of IL-17A and Il-17F), IL-21 and IL-22. Functionally, Th17 cells play a role in host defense against extracellular pathogens by mediating the recruitment of neutrophils and macrophages to infected tissues. Moreover, it is becoming evident that aberrant regulation of Th17 cells may play a significant role in the pathogenesis of multiple inflammatory and autoimmune disorders.

Reactivity	Human
Components	Anti-Human IL-17A (eBio64Dec17) FITC (cat. 11-7179): 25 tests (0.125 µg/5 µl test)* Anti-Human IL-17F (SHLR17) PE (cat. 12-7169): 25 tests (0.5 µg/5 µl test)* Anti-Human IL-22 (22URTI) PerCP-eFluor® 710 (cat. 46-7229): 25 tests (0.015 µg/5 µl test)* Anti-Human IL-21 (3A3-N2) eFluor® 660 (cat. 50-7219): 25 tests (0.125 µg/5 µl test)* Anti-Human CD4 (RPA-T4) eFluor® 450 (cat. 48-0049): 25 tests (0.25 µg/5 µl test)* IC Fixation Buffer (cat. 00-8222): 20 ml. This solution is at a 1X working concentration and contains 4% Paraformaldehyde, which is toxic and suspected carcinogen. Contact with eyes, skin and mucous membranes should be avoided. Permeabilization Buffer (10x) (cat. 00-8333): 100 ml. Dilute to 1X with deionized/distilled water and store at 4°C. Caution: Harmful if swallowed or irritant by contact. Wear proper protective clothing and gloves. Note: The 10X Permeabilization Buffer has a natural tendency to precipitate, however, its function is not affected by this. To clarify, the solution can be filtered after dilution to 1X working solution. *A test is defined as the mouse of antibody to use for 1 million cells in a 100 µl staining volume.
