Biological Description

Biological Information	Measured by its binding ability in a functional ELISA. Immobilized recombinant human IL13RA2 at 8 μg/ml (100 μl/well) can bind IL13 with a linear range of 0.25-8.0 ng/ml.
Description	IL-13 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 39 kDa and the accession number is AAK53823.1.
Species	Human
Expression System	HEK293 Cells
Tag	N-hFc
Accession Number	AAK53823.1
Synonyms	IL-13,ALRH,interleukin 13,P600
Construction	The mature form of Human IL13 (AAK53823.1) (Gly 21-Asn 132) was fused with the Fc region of Human IgG1 at the N-terminus.
Protein Purity	> 98 % as determined by SDS-PAGE
Molecular Weight	39 kDa (predicted)
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research Background	Interleukin 13 (IL-13) is a single-chain glycosylated polypeptide, which belongs to the IL-13/IL-4 family. IL-13 protein is secreted by many cell types, but especially by T helper type 2 (Th2) cells. IL-13 exerts its effects through a multi-subunit receptor comprising the alpha chain of the IL-4 receptor (IL-4Rα) and at least one of two known IL-13-specific binding chains (IL-13 Rα1 and IL-13 Rα2). As a cytokine, IL-13 protein is critical in regulating inflammatory, immune responses, and diseases. Also, it inhibits the production of pro-inflammatory cytokines and chemokines, and thus down-regulates macrophage activity. IL-13 protein and antibody are more importantly implicated as a central mediator of immunoregulatory processes in various cell types.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
