pFUSE-Fc, a family of plasmids for the construction of Fc-Fusion proteins
InvivoGen offers a collection of pFUSE-Fc plasmids developed to facilitate the expression and production of Fc-Fusion proteins, by fusing a sequence encoding a given protein to the Fc region of an immunoglobulin (Ig).
Fc-fusion proteins are molecules consisting of an IgG-Fc domain fused to a protein of interest, such as an extracellular domain of a receptor, ligand, enzyme, or peptide. The Fc domain comprises the CH2 and CH3 regions of the IgG heavy chain and the hinge region. Fusion to an Fc domain gives the hybrid protein additional biological and biophysical properties.
InvivoGen’s pFUSE-Fc collection offers:
- A large choice of Fc regions from different species: human, mouse, rat and rabbit
- Fusion of the Fc domain to the C-terminus (pFUSE-Fc) or N-terminus (pFUSEN-Fc) of a target protein

- Fc regions without introns (pFUSE-Fc) or with introns (pINFUSE-Fc)
- Native Fc regions or engineered Fc regions with altered effector functions (Engineered Fc pFUSE-Fc Vectors)
- Fc regions tagged with Lucia luciferase (pFUSE-Lucia-Fc) or SEAP (pFUSE-SEAP-Fc) for easy screening and detection of recombinant clones
