分子别名 (Synonym)
IgG1; Igh-4; RGD1359539; VH7183
来源/表达系统 (Source)
Recombinant Human IgG1 Fc is expressed from HEK293 without tag.It contains Asp104-Lys330 [Accession | P01857-1].
分子量
The protein has a predicted MW of 25.5 kDa. Due to glycosylation, the protein migrates to 31-33 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 1 EU per μg by the LAL method.
纯度 (Purity)
> 95% as determined by Bis-Tris 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)
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.
