为了开发一种在荧光标记中具有最佳性能的链霉亲和素-生物素系统,在本期《细胞化学生物学》中,Jacobsen等人进行了研究。(2017)专注于通过赖氨酸突变改变链霉亲和素上存在的氨基的表面密度。发现只含有一个游离氨基的链霉亲和素突变体优于其他链霉亲和素突变体,并被命名为Flavidin,以表示对荧光团友好的链霉亲和素。
In order to develop a streptavidin-biotin system with optimal performance in fluorescent labeling, in this issue ofCell Chemical Biology, Jacobsen et al. (2017) focused on changing the surface density of amino groups present on streptavidin via lysine mutagenesis. The streptavidin mutant containing only one free amino group was found superior to other streptavidin variants and was named Flavidin for fluorophore-friendly streptavidin.
