恺佧生物科技（上海）有限公司

表达区间及表达系统（Source）	Recombinant Human B7-H4 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Phe29-Ala258 [Accession \| Q7Z7D3-1].
分子量大小（Molecular Weight）	The protein has a predicted MW of 28.2 kDa. Due to glycosylation, the protein migrates to 52-68 kDa based on Bis-Tris PAGE result.
纯度（Purity）	>95% as determined by Bis-Tris PAGE >95% 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.
