Active Recombinant Human EGF protein(Asn971-Arg1023), hFc-tagged

• Cat.No.: EGF-201H
• Product Overview: Recombinant Human EGF (NP_001954.2) (Asn 971-Arg 1023) was expressed in HEK293, fused with the Fc region of Human IgG1 at the N-terminus.

Specification

• Source: HEK293
• Species: Human
• Tag: N-hFc
• Protein length: Asn971-Arg1023
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured in a cell proliferation assay using Balb/C 3T3 mouse embryonic fibroblast cells. The ED50 for this effect is typically 0.3-1.5 ng/mL.
• Molecular Mass: The recombinant human Fc/EGF chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 290 amino acids and has a calculated molecular mass of 33 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhFc/EGF monomer is approximately 37 kDa due to the glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• 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.
