Detection of Biotinylated Proteins in Polyacrylamide Gels

The high-affinity binding of biotin and avidin has been used as a molecular tool in a wide range of biotechnology, biodiagnostics and medical treatments. Avidin is a tetrameric glycoprotein that tetramerizes biotinylated proteins. Biotinylation can not only increase the binding affinity of avidin, but also increase the multivalency and improve the functionality of the protein. In addition to the in vitro biotinylation of the target protein, in vivo biotinylation applied to the overexpression of recombinant proteins in E. coli is valuable in various fields such as proteome research. Currently, biotinylated proteins after electrophoresis can be detected directly in gels using avidin-fluorescein conjugates and fluorescence image analyzers. The method can also be used to specifically detect the biotinylated protein on the cell surface of Escherichia coli, and the detection method has high sensitivity, strong specificity and simple operation. Alfa Chemistry's research team is composed of experienced researchers who can choose appropriate strategies according to the characteristics of customers' samples, support efficient data analysis, and provide customers with efficient protein biotinylation detection services.
