Human antibody mammalian expression vectors for recombinant antibody production, antibody isotype switching, and antibody engineering research. Fusion BioLabs offers heavy-chain expression vectors for human IgG1, IgG2, IgG3, IgG4, IgA1, IgA2, IgD, IgE, and IgM, together with compatible human kappa and lambda light-chain expression vectors.
These plasmid backbones support the expression of full-length human antibodies following insertion of the appropriate variable-region sequences. Select compatible heavy-chain and light-chain vectors based on the desired antibody isotype and light-chain type.
