Avidin-biotin System Service

Avidin is a protein found in birds and amphibians that has a high affinity for biotin. Biotin is a cofactor that functions in multikaryotic eukaryotic processes. The interaction between avidin and biotin is the strongest known and is ideal for purification and detection strategies. The avidin-biotin system is a typical biological reaction amplification system widely used in biochemical analysis, medical diagnosis, localization monitoring, affinity purification and drug delivery. The avidin-biotin system can be combined with a variety of labels, making biological detection more sensitive. Based on the robust interaction between biotin and avidin, a variety of detection systems have been derived for broader applications. The avidin-biotin system has shown great advantages in practical applications, mainly high sensitivity, high specificity, high stability and wide applicability. Alfa Chemistry supports the expansion of the application of avidin-biotin system in the biological field, and also supports customized services, insisting on meeting customers' needs with high-quality services.

The Services

Biotin-avidin system is widely used in biological diagnosis, drug delivery and biological analysis, and is an important tool for biological research. Alfa Chemistry researchers have a professional team with many years of experience in related fields, a professional quality control platform, and can provide complete biotin-avidin services, including but not limited to:

• Avidin-biotin system for delivery of biomolecules

The avidin-biotin system is used in nano-delivery systems for drugs, including small molecule drugs, small bioassays, antibodies, proteins, vaccines, monoclonal antibodies and nucleic acids.

• Pretargeting strategy using avidin-biotin system

The multifunctionality of pretargeting offers great application potential for tumor diagnosis and therapy, but its development still faces great challenges.

• Avidin-biotin for delivery of diagnostic reagents

Biotin and avidin have strong affinity, and the system has good binding stability and high specificity. The avidin-biotin system can construct a multi-stage signal amplification system, which can be widely used in the fields of immunohistochemistry, enzyme-linked immunosorbent assay, biological diagnosis, gene probe and molecular biology.

• Avidin-biotin complexes for bioanalytical applications

The powerful biotin-avidin complex system serves as an effective research tool in the field of biological research, including biodiagnostics and gene therapy. Alfa Chemistry strives to expand the application in the field of biomolecules, including: affinity chromatography, immunodiagnosis, gene probes and localization observation.
