Collection: Bioconjugation

Bioconjugation — contains reagents for bioconjugation, ranging from biotin and streptavidin, copper-free click reagents, functional group blocking reagents, and functionality creating reagents, to N-terminal cysteine-specific reagents, PEGylation, and zero-length crosslinkers. This group supports the directed formation of covalent bonds between biomolecules such as proteins, peptides, and antibodies.

Bioconjugation reagents are used by molecular biology researchers and antibody-drug conjugate developers to link proteins, peptides, or oligonucleotides specifically at defined positions. PEGylation reagents are used to modify the solubility and stability of biomolecules, while zero-length crosslinkers and copper-free click reagents enable conjugation under milder conditions for sensitive samples such as living cells.

Example products in this collection: TCI A0170 1071-93-8 Adipic Dihydrazide, TCI B5546 1309649-57-7 Biotin-PEG4-Azide, TCI A0296 156-57-0 2-Aminoethanethiol Hydrochloride, TCI B5560 663171-32-2 Biotin-PEG4-Amine, TCI V0155 159857-79-1 Val-Cit-PAB-OH, TCI B5562 721431-18-1 Biotin-PEG4-propionic Acid, TCI U0145 127062-22-0 Sulfo-NHS-LC-Biotin (2mg*3), TCI B5563 1808990-66-0 Biotin-PEG6-Maleimide.

Pay attention to the specificity of reactive groups toward target amino acid residues, the length of PEG spacers, and the compatibility of reaction conditions with the structural integrity of the biomolecule being conjugated. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
