纯度
> 95 % as determined by SDS-PAGE
内毒素
< 1.0 EU per μg of the protein as determined by the LAL method
生物活性
1. Measured by its binding ability in a functional ELISA. 2. Immobilized human HGF (Cat:10463-HNAS) at 10 μg/mL (100 μl/well) can bind canine c-MET (Cat:70008-D08H), The EC50 of canine c-MET (Cat:70008-D08H) is 7 ng/mL.
蛋白构建
A DNA sequence encoding the extracellular domain of canine MET (NP_001002963.1) (Met 1-Leu 935) was expressed, with a polyhistidine tag at the N-terminus.

分子量
The recombinant canine c-Met is a disulfide-linked heterodimer composed of proteolytically cleaved α and β subunits. Each α and β subunit together consists of 922 amino acids and has a predicted molecular mass of 103 (α =33 + β =70) kDa. As a result of glycosylation, the apparent molecular mass of the canine c-Met is approximately 42-47 kDa and 85-95 kDa respectively in SDS-PAGE under reducing conditions.
缓冲液
Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式
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.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

c-MET 背景信息

Hepatocyte growth factor receptor (HGFR), also known as c-Met or mesenchymal-epithelial transition factor (MET), is a receptor tyrosine kinase (RTK) that is overexpressed and/or mutated in a variety of malignancies. HGFR protein is produced as a single-chain precursor, and HGF is the only known ligand. Normal HGF/HGFR signaling is essential for embryonic development, tissue repair, or wound healing, whereas aberrantly active HGFR has been strongly implicated in tumorigenesis, particularly in the development of invasive and metastatic phenotypes. HGFR protein is a multifaceted regulator of growth, motility, and invasion, and is normally expressed by cells of epithelial origin. Preclinical studies suggest that targeting aberrant HGFR signaling could be an attractive therapy in cancer.
