Human IL-13 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human IL-13 Protein is expressed from E.coli without tag.
It contains Gly21-Asn132 [Accession | AAK53823].

分子量大小(Molecular Weight)

The protein has a predicted MW of 12.34 kDa same as Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 0.1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

Human IL-13 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human IL-13 is greater than 95% as determined by SEC-HPLC.

Cell Based Assay

Measured in a cell proliferation assay using TF1 human erythroleukemic cells. The ED50 for this effect is typically 0.5-3 ng/mL. (QC Test)

ELISA Data

Immobilized Human IL-13, No Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human IL-13Ra2, His Tag with the EC50 of 3.6ng/ml determined by ELISA. (QC Test)

BLI Data

Loaded Human IL-13Ra2, His Tag on Anti-His-Biosensor can bind Human IL-13, No Tag with an affinity constant of 0.63 nM as determined in BLI assay (Gator® Prime).

背景(Background)

Interleukin-13 (IL-13) is a monomeric 17 kDa immunoregulatory cytokine that plays a key role in the pathogenesis of allergy, cancer, and tissue fibrosis. It is secreted by several helper T cell subsets, NK cells, mast cells, eosinophils, basophils, and visceral smooth muscle cells. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Positively regulates IL31RA expression in macrophages (By similarity).

DISCLAIMER

KACTUS Human IL-13 Protein is for research or ex vivo cell processing use, not for human or animal in vivo application.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
