Subfunctionalization of the Ruby2-Ruby1 gene cluster during the domestication of citrus. Huang D, et al,Nature Plants,2018
Application: Pull-down assay
Review: Competitive binding assays of CgRuby1 and CgRuby2Short binding to CgbHLH1. The mixture of HIS-CgRuby1 and FLAG CgRuby2Short was added to immobilized GSTCgbHLH1. The precipitates were detected using western blot analysis with anti-HIS, anti-FLAG or anti-GST antibodies. The gradient indicates the increasing amount of FLAG-CgRuby2Short. These experiments were repeated independently twice with similar results.
