pFUSE-hIgG1e4-Fc1 is a cloning plasmid for the generation of a Fc-fusion protein expressing the Fc region (CH2 and CH3 domains) of the human IgG1 heavy chain mutated E333 and the hinge region. The hinge serves as a flexible spacer between the two parts of the Fc-fusion protein, allowing each part of the molecule to function independently.

hIgG1e4-Fc2 additionally features the IL2 signal sequence for the generation of Fc-Fusion proteins derived from proteins that are not naturally secreted.


Isotype: IgG1 human

- Increased binding to FcγRIIIa
- Increased ADCC and CDC

Both plasmids are selectable with Zeocin™.


• 20 μg of lyophilized DNA
• 4 pouches of E. coli Fast-Media® Zeo (2 TB and 2 Agar)
