Active Recombinant Human ENG protein, hFc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : hFc | Form : Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : 1. Measured by its ability to bind biotinylated Human TGFRB1 in a functional ELISA.2. Measured by its ability to bind biotinylated Human ALK1-Fc in functional Elisa. | Molecular Mass : The recombinant human CD105/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 799 amino acids and has a predicted molecular mass of 87.5 kDa. As a result of glycosylation, rhCD105/Fc monomer migrates as an approximately 115-120 kDa protein in SDS-PAGE under reducing conditions. | Protein Length : Met1-Gly586 | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°CStore it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
