Human IL-15RA&IL-15 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human IL-15RA&IL-15 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ile31-Ser108(IL-15RA)&Asn49-Ser162(IL-15).[Accession | Q13261-1(IL-15RA)&P40933-1(IL-15)]

分子量大小(Molecular Weight)

The protein has a predicted MW of 23.8 kDa. Due to glycosylation, the protein migrates to 26-28 kDa&30-32 kDa based on Tris-Bis PAGE result.

内毒素(Endotoxin)

Less than 1EU per ug by the LAL method.

纯度(Purity)

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

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 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

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