pFUSE-hIgG1e3-Fc1 is a cloning plasmid for the generation of a Fc-fusion protein expressing the Fc region (CH2 and CH3 domains) of the mutated human IgG1 heavy chain 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.  The engineered hIgG1e3 Fc contains the following mutations: E233P/L234V/L235A/ΔG236 + A327G/A330S/P331S.

hIgG1e3-Fc2 additionally features the IL2 signal sequence for the generation of Fc-Fusion proteins derived from proteins that are not naturally secreted.

DISCLAIMER: pFUSE-hIgG1e3 plasmids featuring the IgG1e3 engineered Fc are sold by InvivoGen under a limited license from Cambridge Enterprise Limited (International Publication Number WO 99/58572).
