恺佧生物科技（上海）有限公司

表达区间及表达系统（Source）	Recombinant Human IL-3 R alpha/CD123 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Thr19-Arg305 [Accession \| P26951-1].
分子量大小（Molecular Weight）	The protein has a predicted MW of 59.7 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Bis-Tris PAGE result.
纯度（Purity）	> 90% as determined by Bis-Tris PAGE > 90% as determined by HPLC
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
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 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
