ABOUT
Heavy chain constant region expression plasmid - Mouse IgG3 - Lucia
pFUSE-Lucia-CHIg-mG3 is a cloning plasmid that expresses the constant region of the murine IgG3 heavy chain. 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.
pFUSE-Lucia-CHIg-mG3 contain the secreted luciferase (Lucia) gene upstream of the MCS and the CH region to serve as a tag to facilitate the detection and quantification of recombinant antibodies.
All products are for research use only, and not for human or veterinary use.

Details
1- Schematic representation of a Lucia luciferase-tagged antibody
2- Luciferase activity of Lucia-tagged anti-hTNF-α antibodies.
CHO cells were stably co-transfected with a heavy chain expressing plasmid, pFUSE-Lucia-TNF-CHIg-hA2m1 (TNF-CHIg-hA2m1) or pFUSE-Lucia-TNF-CHIg-hG1 (TNF-CHIg-hG1) and a light chain expressing plasmid, pFUSE2-TNF-CLIg-hk (TNF-CLIg-hk) to generate Lucia-tagged anti-hTNF-α antibodies, Lucia-anti-hTNF-α-hIgA2m1and Lucia-anti-hTNF-α-hIgG1, of human IgAm2 and human IgG1 isotypes, respectively. pFUSE2-CLIg-hk (CLIg-hk), which expresses no VL, and pSELECT-blasti-mcs (mcs) were used as negative controls. Supernatants
were collected and the luciferase levels determined using QUANTI-Luc™. Only the cells co-producing a Lucia-anti-hTNF-α heavy-chain and an anti-hTNF-α light chain displayed luciferase activity.
3- Neutralizing activity of anti-hTNF-a antibodies
The activity of anti-hTNF-α-hIgA2m1 and Lucia-anti-hTNF-α-hIgA2m1 antibodies, purified from the supernatants of CHO transfected cells, was determined by performing an TNF-α neutralizing assay. Both antibodies display similar neutralizing activities, thus fusion of the Lucia luciferase tag at the N-terminus of the heavy chain does not alter the functionality of the antibody.
