Biotinylated Cynomolgus IL-2 R beta/CD122 Protein (Primary Amine Labeling)

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Cynomolgus IL-2 R beta/CD122 Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus.
It contains Ala27-Asp239 [Accession | Q38J85].

分子量大小(Molecular Weight)

The protein has a predicted MW of 25.6 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.

纯度(Purity)

>95% as determined by Bis-Tris PAGE
>90% as determined by HPLC

内毒素(Endotoxin)

Less than 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)

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

Biotinylated Cynomolgus IL-2 R beta on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Biotinylated Cynomolgus IL-2 R beta is greater than 90% as determined by SEC-HPLC.

SPR Data

Biotinylated Cynomolgus IL-2 R beta, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human IL-2, No Tag with an affinity constant of 0.148 μM as determined in SPR assay (Biacore T200).

背景(Background)

IL-2 R beta is a member of the cytokine receptor superfamily. Human IL-2 R beta cDNA encodes a 551 amino acid residue precursor Type I membrane protein with a 26 residue signal peptide, a 214 residue extracellular region, a 25 residue transmembrane region and a 286 residue cytoplasmic domain. Functional IL-2 receptors can exist in two affinity states on cell surfaces, the high affinity complex consisting of heterotrimers of the alpha, beta, and gamma chains, and the intermediate affinity complex comprising heterodimers of the beta and gamma chains.

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