Since northern blot uses size-dependent separation, this technique can not only determine the abundance but also the sizes of transcript of interest. It can be a. Principio y Aplicación blot (secado) o blotting para referirse a esta técnica y actualmente se conoce como Southern blot Southern Northern Western Blot. The eastern blot is a biochemical technique used to analyze protein post translational . compares the common blotting methods (Southern, northern, and western), and states that “the eastern blot, however, exists only in test questions.”.
