分子别名（Synonym）:MTC,p140-TrkA,TRK,Trk-A,TRK1,TRKA

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 recombinant human NTRK1/Fc is a disulfide-linked homodimer. The reduced monomer consists of 598 amino acids and has a predicted molecular mass of 66 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh NTRK1/Fc monomer is approximately 85-95 kDa due to glycosylation.

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

生物活性(Activity)：Measured by its ability to inhibit NGF-induced proliferation of TF-1 human erythroleukemic cells. The ED50 for this effect is typically 0.04-0.15 μg/ml in the presence of 10 ng/ml of recombinant human NGF.

表达区间（Protein Construction）：A DNA sequence encoding the human NTRK1 (NP_002520.2) extracellular domain (Ser 2-Pro 382) was fused with the C-terminal polyhistidine-tagged 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.
