Mouse IL-2 R alpha/CD25 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Mouse IL-2 R alpha/CD25 Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Glu22-Lys236 [Accession | P01590].

分子量大小(Molecular Weight)

The protein has a predicted MW of 25.76 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on 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 1EU per μg by the LAL method.

制剂(Formulation)

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

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

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

Mouse IL-2 R alpha on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Mouse IL-2 R alpha is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Mouse IL-2 R alpha, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Mouse IL-2, His Tag with the EC50 of 0.21μg/ml determined by ELISA (QC Test).

SPR Data

Mouse IL-2 R alpha, His Tag immobilized on CM5 Chip can bind Mouse IL-2, His Tag with an affinity constant of 30.49 nM as determined in SPR assay (Biacore T200).

背景(Background)

IL-2 receptor alpha (IL-2 R alpha), also known as Tac antigen and as CD25, was initially identified as a 55 kDa membrane glycoprotein that is capable of binding IL‑2.eceptor for interleukin-2. The receptor is involved in the regulation of immune tolerance by controlling regulatory T cells (TREGs) activity. TREGs suppress the activation and expansion of autoreactive T-cells.

分子别名(Synonyms)

CD25; IDDM10; IL-2 R alpha; IL2R; IL2RA; p55; TCGFR

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