INTERLEUKIN 17 HUMAN

General description

The gene IL17A (interleukin 17A), also referred to as IL-17, is mapped to human chromosome 6p12.2. The gene contain three exons and encodes a proinflammatory cytokine produced by activated T cells.

Biochem/physiol Actions

The cytokine interleukin 17A is involved in the activation of proinflammatory cytokines, chemokines, and cell adhesion molecules in several cell types such as, macrophages, dendritic cells, T cells, synovial cells, and endothelial cells. Overexpression of this protein has been associated with rheumatoid arthritis, systemic lupus erythematosus, Behcet′s disease, allograft rejection, nephritic syndrome, asthma, and multiple sclerosis. In mice, it has been observed to be implicated in the development of allergic and autoimmune diseases. Polymorphism in IL17A gene has been associated with lung cancer.

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C.
