Description

Initially cloned from cDNA libraries of activated T cells, human IL-13 is an immunoregulatory cytokine produced by Th2 type helper T cells in response to signaling through the T cell antigen receptor and by mast cells and basophils upon cross-linkage of the high-affinity receptor for immunoglobulin E (IgE). IL 13 is a key mediator in the pathogenesis of allergic inflammation sharing many functional properties with IL-4 including the alpha subunit of the IL-4 receptor (IL-4Rα). IL-13 mediates its effects by interacting with a complex receptor system comprised of IL-4Rα and two IL-13 binding proteins, IL-13Rα1 and IL-13Rα2. Ligation of the IL-13 receptor complex results in signaling via the insulin receptor substrate (IRS)-1 and 2 and STAT-6 pathways. IL-13 has been implicated in airway hypersensitivity, mucus hypersecretion, inflammatory bowel disease, and parasitic nematode expulsion. In vitro studies suggest IL-13 decreases SARS-CoV-2 entry to bronchial epithelial cells.

Product Details

Source
Human IL-13, amino acid (Gly21-Asn132) (Accession: # X69079) was expressed in E.coli.
Molecular Mass
The 112 amino acid recombinant protein has a predicted molecular mass of 12.3 kD. The DTT-reduced and non-reduced protein migrate at approximately 9 kD by SDS-PAGE. The N-terminal amino acid is Gly.
Purity
> 95%, as determined by Coomassie stained SDS-PAGE.
Formulation
0.1 µm filtered protein solution is in 10 mM NaH2PO4, 150 mM NaCl, pH 7.2
Endotoxin Level
Less than 0.1 EU per µg of protein as determined by the LAL method.
Concentration
25 µg and 100 µg sizes are bottled at 0.5 mg/mL
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin the vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
Activity
Human IL-3 induces proliferation of human TF-1 cells in a dose-dependent manner. The ED50 for this effect is 0.5 – 3.0 ng/mL.
Application
