Human IgG1 Mammalian Expression Vector with increased half-life

Product Overview                                Data Sheet                    Protocol

pFB-CHIg-hG1e7 is a cloning vector that expresses the human IgG1 heavy chain constant region with T307A/E380A/N434A mutations. It is a constitutive mammalian expression vector designed to deliver exceptionally high levels of antibody expression. This circular vector features an enhanced, full-length CMV promoter and other expression elements that typically enable higher expression levels. It can be used in suspension-adapted cells, such as Expi293F™ and ExpiCHO™, for transient protein expression. Additionally, it can serve as a Geneticin®-selectable expression plasmid for engineering stable cell lines. The vector carries an ampicillin resistance gene.

Materials required for Fc engineered antibody generation

 

Steps for Fc engineered antibody generation

  • Cloning your heavy chain variable region (VH) into pFB-CHIg-hG1e7 vector to make heavy chain expression plasmid.
  • Cloning your light chain variable region (VL) into pFB-CLIg-hk or pFB-CLIg-hl vector to make light chain expression plasmid.
  • Co-transfecting both heavy chain and light chain expression plasmids into your desired mammalian cell (such as CHO, HEK293) for Fc engineered antibody production.
