分子别名（Synonym）:ACEH

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile 100mM Glycine, 10mM NaCl, 50mM Tris, pH 7.5

分子量（Molecule Mass）：The recombinant human ACE2/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 961 amino acids and predicts a molecular mass of 110.3 kDa. As a result of glycosylation, the rhACE2/Fc monomer migrates as approximately 145-150 kDa band in SDS-PAGE under reducing conditions.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：1. Using the Octet RED System, the affinity constant (Kd) of human AEC2-Fc (Cat:H1332-202H) bound to Spike (HCoV-EMC/2012) (Cat:B) was 6 nM.

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser 2-Ser 740) of human ACE2 precursor (NP_068576.1) was expressed with the fused Fc region of human IgG1 at the C-terminus.

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.
