Bioconjugation is a chemical strategy to form a stable covalent bond between two molecules, at least one of which is a biomolecule. Of all biomolecules, proteins are vital substrates for bioconjugation reactions.
Common biochemical conjugation includes:
The most common bioconjugation are:
Bioconjugation is a novel technology that improves biological activity from biopharmaceutical aspects and provides spatial and temporal distribution. Moreover, this strategy opens up new prospects for the delivery of drugs, peptides, enzymes, and oligonucleotides. Mechanistically, site-specific delivery can be achieved by tailoring the conjugate to an inactive prodrug and designing a polymer-drug bond that is readily cleaved by a specific enzyme or pH. These prodrugs significantly alter the cell entry mechanism, pharmacokinetic treatment, and ultimately targeted drugs. Bioconjugate drugs include antibody-drug complexes (ADC), PEGylated proteins, siRNA complexes and vaccine complexes.

Coupled small molecules are used as probes for rigorous biochemical analysis, and non-fluorescent small molecules such as biotin are used as mechanical probes.
Qualitative and quantitative analysis of clinical samples is essential for diagnosing early disease, and the high specificity of antibody-antigen interaction avoids sample purification.
Bioconjugation is used in various industries. For example, isomerized fumaric acid and malic acid are used in the food industry for residue detection; the pharmaceutical industry uses immobilized enzymes for drug synthesis, drug detection, doping detection, etc.
Custom Bioconjugation Services involve the tailored linking of biomolecules such as proteins, antibodies, or nucleic acids to other molecules like drugs, peptides, or fluorophores. These services are designed to meet specific research or therapeutic needs, optimizing the functionality of the conjugates for diverse applications.
Various biomolecules can be conjugated, including antibodies, proteins, oligonucleotides, enzymes, and peptides. These biomolecules are conjugated to other entities such as small molecules, nanoparticles, or fluorophores to enhance their properties or enable targeted delivery.
Custom Bioconjugation is commonly used in drug delivery systems, diagnostic assays, immunoassays, and therapeutic development. It is particularly valuable in creating targeted treatments, improving drug stability, and enhancing the detection of biomolecules in various analytical methods.
