分子别名 (Synonym)
CD19; B4; CVID3; Leu-12; MGC12802
来源/表达系统 (Source)
Recombinant Mouse CD19 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Arg19-Gly287 [Accession | P25918].
分子量
The protein has a predicted MW of 30.7 kDa. Due to glycosylation, the protein migrates to 55-68 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 1 EU per ug by the LAL method.
纯度 (Purity)
> 90% as determined by Bis-Tris PAGE
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)
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.
