Methods are provided for making bispecific antibodies and antibody conjugates comprising site-specifically cross-linking two or more antibodies, antibody fragments or Fc-fusion proteins. Also provided are compositions and uses for the bispecific antibodies and antibody conjugates. The bispecific antibodies may be used to treat a disease or condition. Also provided are methods for site-specifically conjugating a liposome, an mRNA or an siRNA to an antibody, and uses of the antibody-conjugated liposome, mRNA or siRNA.

Site-specific crosslinking of antibodies

Methods of using viruses labeled with alkyne-modified biomolecules, such as fatty acids, carbohydrates and lipids, to treat a plant, an insect or an animal infected with a virus or to increase the infectivity of a virus, such as the human immunodeficiency virus, are provided. Also provided are methods of labeling a virus, such as human immunodeficiency virus, with an alkyne-modified biomolecule, such as a fatty acid, a carbohydrate, or an isoprenoid lipid. The viruses labeled with alkyne-modified biomolecules may be combined with a pharmaceutically acceptable excipient to produce a pharmaceutical composition, optionally containing another anti-viral agent and/or a delivery agent, such as a liposome.

Methods for increasing the infectivity of viruses utilizing alkyne-modified fatty acids

The present invention generally relates to methods of functionalizing proteins, particularly antibodies, at oligosaccharide linkages, methods of humanizing antibodies by modifying glycosylation, as well as to novel antibodies linked to modified oligosaccharides. The invention further relates to kits that may be used to produce the antibodies of the invention.

Oligosaccharide modification and labeling of proteins

Methods of using azide-modified biomolecules, such as fatty acids, carbohydrates and lipids, to treat a plant, an insect or an animal infected with a virus or to inhibit infectivity of a virus, such as the human immunodeficiency virus, are provided. Also provided are methods of labeling a virus, such as human immunodeficiency virus, with an azide-modified biomolecule, such as a fatty acid, a carbohydrate, or an isoprenoid lipid. Also, provided are methods of tracking a virus in vivo, with an azide-modified biomolecule, such as a fatty acid, a carbohydrate, or an isoprenoid lipid. The azide-modified biomolecules may be combined with a pharmaceutically acceptable excipient to produce a pharmaceutical composition, optionally containing another anti-viral agent and/or a delivery agent, such as a liposome.

Anti-viral azide containing compounds

The present invention relates to methods for the labeling of nucleic acid polymers in vitro and in vivo. Certain methods are provided that include a [3+2] cycloaddition between a nucleotide analogue incorporated into a nucleic acid polymer and a reagent attached to a label. Other methods are provided that include a Staudinger ligation between a nucleotide analogue incorporated into a nucleic acid polymer and a reagent comprising a substituted triarylphosphine attached to a label. Such methods do not require fixation and denaturation and therefore can be applied to the labeling of nucleic acid polymers in living cells and in organisms. Also provided are methods for measuring cellular proliferation. In these methods, the amount of label incorporated into the DNA is measured as an indication of cellular proliferation. The methods of the invention can be used in a wide variety of applications including clinical diagnosis of diseases and disorders in which cellular proliferation is involved, toxicity assays, and as a tool for the study of chromosomes' ultrastructures.

Methods and compositions for labeling nucleic acids

Provided in certain embodiments are new methods for forming azido modified biomolecule conjugates of reporter molecules, carrier molecules or solid support. In other embodiments are provided methods for enzymatically labeling a biomolecules with an azide group.
