Acitve Recombinant Human TNFSF14 protein(Asp74-Val240), rFc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : N-rFc | Protein length : Asp74-Val240 | Form : Lyophilized from sterile 50 mM Tris, 100 mM NaCl, pH 8.5. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : Measured in a cell prolifeRation assay using Human umbilical vein endothelial cells (HUVEC). The ED50 for this effect is typically 5-25 ng/mL. | Molecular Mass : The recombinant Human TNFSF14 consists of 418 amino acids and predicts a molecular mass of 45.7 kDa. | Endotoxin : | Purity : > 90 % as determined by SDS-PAGE | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store 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.
