Protein Labeling & Crosslinking

Convenient labeling kits and reactive dyes for the direct attachment of Invitrogen Alexa Fluor and other dyes for 10 μg to 1 mg of proteins or antibodies.

Reagents containing reactive ends to specific functional groups on proteins and antibodies, enabling the covalent joining or two or more biomolecules for the study of protein function and interaction.

Reagents and kits to chemically tag and label antibodies, proteins, and peptides with biotin or desthiobiotin at particular amino acid functional groups to create labeled antibody or other probes for streptavidin affinity binding, purification, and detection.

Unique single-use packaging format for crosslinking, labeling and reducing reagents in 1 or 2 mg quantities, eliminating the need to weigh out small amounts of dry or viscous chemicals.

Reagents to modify proteins by crosslinking, fragmenting, cleaving, denaturing, reducing disulfides, or attaching functional groups to study protein function and interactions.

Crosslinking, labeling and reducing reagents that require long-term, consistent performance and robust chemical characterization and documentation.

Activated linear and branched derivatives of polyethylene glycol (PEG) for PEGylation and PEG-modification of peptides and proteins via primary amines and sulfhydryl groups to increase solubility, prolong stability, and reduce immunogenicity.
