Labeling reagents

Labeling reagents play a crucial role in bioconjugation, which is the process of attaching synthetic molecules or probes to biomolecules such as proteins, nucleic acids, or carbohydrates. This enables researchers to modify biomolecules with precision, facilitating various applications in chemical biology, drug discovery, and diagnostics.
Common types of labeling reagents include enzyme-linked labeling reagents, biotin-streptavidin labeling reagents, antibody-based labeling reagents and click chemistry labeling reagents.
