pFUSE-CHIg general plasmid map

Human IgG1 heavy chain constant region with reduced ADCC and CDC

 

pFUSE-CHIg-hG1e3 is a cloning plasmid that expresses the human IgG1 heavy chain constant region with E233P / L234V / L235A / deltaG236 + A327G / A330S / P331S mutations. It contains a multiple cloning site upstream of the constant region to enable cloning of the heavy chain variable region. This plasmid is designed for antibody generation when co-transfected into mammalian cells with the light chain variable region cloned into pFUSE-CLIg.

pFUSEss-CHIg-hG1e3 additionally features the IL2 signal sequence to allow the secretion of recombinant antibodies generated using fragment antigen-binding (Fab) or single-chain variable fragment (scFv)  fragments selected from phage display libraries that lack a signal sequence.

 

Key features of pFUSE-CHIg-hG1e3

  • Encodes the human IgG1e3 CH constant region (E233P / L234V / L235A / deltaG236 + A327G / A330S / P331S mutations)
  • Long-lasting expression due to the composite hEF1-HTLV promoter
  • Selectable with Zeocin™ in both bacterial and mammalian cells
  • Available with or without the IL-2 signal sequence

 

DISCLAIMER: pFUSE-CHIg-hG1e3 plasmids featuring the IgG1e3 engineered Fc are sold by InvivoGen under a limited license from Cambridge Enterprise Limited (International Publication Number WO 99/58572).
