Product Description
Recombinant Human IL-9 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln19-Ile144.
Product Background
IL-9 is a pleiotropic cytokine that influences various distinct functions of different target cells such as T cells, B cells, mast cells and airway epithelial cells by activating STAT1, STAT3 and STAT5. Because of its pleiotropic functions, IL-9 has been demonstrated to be involved in several diseases, such as cancer, autoimmunity and other pathogen-mediated immune-regulated diseases. In this review, we focus on the role of Th9 and IL-9-producing cells in allergic asthma.

Purity
> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Form
Lyophilized
Shipping
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22um filtered solution in 20mM Tris, 150mM NaCl (pH 7.5). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
