分子别名 (Synonym)
IL-2RB&IL-2RG; IL-2RG; IL-2R subunit gamma; IL-2R subunit beta; IL-2RB; IL15RB; IL-2 R beta&IL-2 R gamma; IL-2R subunit β; IL-2 R β&IL-2 R gamma; IL-2Rγ; IL-2R γ; IL-2 Rγ; IL-2 R γ
来源/表达系统 (Source)
Recombinant Human IL-2 R beta&IL-2 R gamma Protein is expressed from HEK293 with hFc (IgG1) tag at the C-Terminus of IL-2 R beta and IL-2 R gamma.It contains Ala27-Thr240 (IL-2 R beta) and Leu23-Ala262 (IL-2 R gamma) [Accession | P14784(IL-2 R beta)&P31785-1(IL-2 R gamma)].
分子量
The protein has a predicted MW of 51.3 kDa (IL-2 R beta) and 54.6 kDa (IL-2 R gamma). Due to glycosylation, the protein migrates to 65-70 kDa and 80-100 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 1 EU per μg by the LAL method.
纯度 (Purity)
> 90% as determined by Bis-Tris PAGE
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)
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.
