    摘要: A method of making a glycosylated antibody or antibody fragment having a reactive ketone group on the glycosylated site is provided. The method comprises expressing a cell transfected with a vector encoding an antibody having one or more glycosylation sites in a culture medium comprising a ketone derivative of a saccharide or saccharide precursor and, in the case of an antibody fragment, fragmenting the resulting antibody into an antigen-binding antibody fragment. Methods of making immunoconjugates comprising the glycosylated antibodies or antibody fragments also are provided, wherein the antibody or antibody fragment is reacted with an agent comprising a ketone-reactive group. Glycosylated antibodies and antibody fragments having a reactive ketone group on the glycosylated site, immunoconjugates comprising such antibodies and antibody fragments and in vivo targeting methods using such antibodies, antibody fragments and immunoconjugates also are provided.

    摘要: This invention relates to monovalent and multivalent, monospecific binding proteins and to multivalent, multispecific binding proteins. One embodiment of these binding proteins has one or more binding sites where each binding site binds with a target antigen or an epitope on a target antigen. Another embodiment of these binding proteins has two or more binding sites where each binding site has affinity towards different epitopes on a target antigen or has affinity towards either a target antigen or a hapten. The present invention further relates to recombinant vectors useful for the expression of these functional binding proteins in a host. More specifically, the present invention relates to the tumor-associated antigen binding protein designated RS7, and other EGP-1 binding-proteins. The invention further relates to humanized, human and chimeric RS7 antigen binding proteins, and the use of such binding proteins in diagnosis and therapy.

    摘要: Disclosed are compositions and methods for increasing the longevity of a cell culture and permitting the increased production of proteins, preferably recombinant proteins, such as antibodies, peptides, enzymes, growth factors, interleukins, interferons, hamiones, and vaccines. Cells transfected with an apoptosis-inhibiting gene or vector, such as a triple mutant Bcl-2 gene, can survive longer in culture, resulting in extension of the state and yield of protein biosynthesis. Such transfected cells exhibit maximal cell densities that equal or exceed the maximal density achieved by the parent cell lines. Transfected cells can also be pre-adapted for growth in serum-free medium, greatly decreasing the time required to obtain protein production in serum-free medium. In certain methods, the pre-adapted cells can be used for protein production following transformation under serum-free conditions. The method preferably involves eukaryotic cells, more preferably mammalian cells.
