Biotin Derivatives | ABP Biosciences

Introduction

The interaction between biotin and avidin or streptavidin has been exploited for use in many protein and nucleic acid detection and purification methods. Because the biotin label is stable and small, it rarely interferes with the function of labeled molecules enabling the avidin-biotin interaction to be used for the development of robust and highly sensitive assays. The avidin-biotin detection system allows an almost unlimited number of primary detection reagents (i.e., antibodies, nucleic acid probes and ligands) to be easily captured, immobilized or detected with secondary detection reagents generated by modifying avidin or streptavidin.

Biotin Derivatives are employed in biotechnology as biotinylation reagents. ABP Biosciences offers many biotin reagents to facilitate biotinylation in the lab.
