分子别名（Synonym）:c-erbB-3,c-erbB3,EEBB3,ErbB-3,erbB3-S,HER3,LCCS2,MDA-BF-1,p180-ErbB3,p45-sErbB3,p85-sErbB3

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The mature recombinant human ErbB3/Fc chimera is a disulfide-linked homodimeric protein after the removal of signal peptide. The monomer consists of 862 amino acids and has a calculated molecular mass of 95.4 kDa. As a result of glycosylation, the recombinant monomer migrates as an approximately 130-140 kDa protein in SDS-PAGE under reducing conditions.

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

生物活性(Activity)：Measure by its ability to bind with human NRG1-β1 in a functional ELISA.

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser 2-Thr 643) of human ErbB3 (NP_001973.2) precursor was expressed with the C-terminal fused Fc region of human IgG1.

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.
