    Abstract: The properties of an Fc-containing protein, for example, an antibody, are controlled by altering the sialylation of the oligosaccharides in the Fc region by transfecting the cell line expressing the Fc-containing protein with a vector sequence encoding a sialidase. The modified Fc-containing proteins have therapeutic utility in diseases or conditions in which it is desirable to control the affinity for one or more of the FcγRI, FcγRIIA, and FcγRIIIA receptors, ADCC activity, macrophage or monocyte activation, serum half-life, and avidity.

    Abstract: Antibody expression vectors and plasmids can incorporate various antibody gene portions for transcription of the antibody DNA and expression of the antibody in an appropriate host cell. The expression vectors and plasmids have restriction enzyme sites that facilitate ligation of antibody-encoding DNA into the vectors. The vectors incorporate enhancer and promoter sequences that can be varied to interact with transcription factors in the host cell and thereby control transcription of the antibody-encoding DNA. A kit can incorporate these vectors and plasmids.
