表达区间及表达系统（Source）	Recombinant Human Fc gamma RIIIB/CD16b (NA2) Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gly17-Ser200(NA2). The CD16b NA1 differ with the CD16b NA2 in AA36, 65, 82, and 106.The CD16b NA1 form carries R36, N65, D82, and V106, while the CD16b NA2 form carries S36,S65, N82, and I106 [Accession \| O75015-1].
分子量大小（Molecular Weight）	The protein has a predicted MW of 23.7 kDa. Due to glycosylation, the protein migrates to 47-53 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 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.
