Human CD32b / FCGR2B Protein (

分子别名（Synonym）:CD32,CD32A,CD32B,CDw32,Fc gamma RII,Fc gamma RIIB,FCG2,FcGR,FCGR2,FCGR21,FCGR2A,IGFR2 种属（Species）：Human 表达系统（Expressed Host）：CHO Cells 制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4 分子量（Molecule Mass）：The secreted recombinant human CD32b consists of 183 amino acids and predicts a molecular mass of 20.8 KDa. The apparent molecular mass of the protein is approximately 29 KDa in SDS-PAGE under reducing conditions due to glycosylation. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Measured by its binding ability in a functional ELISA. 表达区间（Protein Construction）：A DNA sequence encoding (Ala46-Pro217) of human CD32b (P31994-1) was expressed,with a C-terminal polyhistidine tag. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
