Biotinylation is a widely employed technique in biochemistry and molecular biology for the modification of peptides, ligands, antibodies, and proteins. By attaching biotin molecules to these biomolecules, researchers can harness the strong affinity between biotin and avidin/streptavidin for various applications, including purification, detection, and immobilization. The versatility of biotinylation allows for the creation of tailored biotin-conjugated biomolecules that maintain their biological activity while offering enhanced functionality.
Various Product Categories
Peptides are often biotinylated at specific residues to enable their capture, detection, or immobilization in various assays. The biotin tag can be introduced at the N-terminus, C-terminus, or at lysine residues, depending on the desired application.
Biotinylated peptides are crucial in applications such as ELISA, Western blotting, and peptide-based affinity purification. Our biotinylated peptides are synthesized with high precision, ensuring consistent labeling and maintaining the biological activity of the peptide.
Ligands, including small molecules and other binding partners, can be biotinylated to facilitate their interaction with target proteins or receptors. Biotinylated ligands are often used in receptor-ligand binding studies, drug screening assays, and affinity purification of protein complexes. The biotin tag does not interfere with the ligand's ability to bind to its target, making these biotinylated ligands ideal for sensitive and specific applications.
Antibodies are frequently biotinylated for use in immunoassays, including ELISA, flow cytometry, and immunoprecipitation. The biotinylation process is carefully controlled to ensure that the antibody retains its antigen-binding capability while providing multiple biotin sites for robust interaction with avidin or streptavidin.
Proteins can be biotinylated to enable their use in various detection and purification protocols. Biotinylated proteins are valuable tools in protein-protein interaction studies, pull-down assays, and as standards in various analytical techniques. The biotinylation of proteins is performed under mild conditions to preserve their structural integrity and functional activity, ensuring reliable results in downstream applications.
