The compass of biomedicine.

In this case, Southern was not a direction, but a scientist: Edwin M. Southern. I Acta Physiologica i caters to a wide variety of research efforts related to physiology - itself one of if not the most diverse discipline of biomedical research. He established a method to split up DNA via electrophoresis and detect specific sequences by hybridization - the Southern blot.4 Methods for detecting specific proteins5 and RNA sequences6 were established soon after, based on the same principle. Subsequently, searching recent I Acta Physiologica i publications for references to "blotting" should provide a reliable and lower bound estimate of the prominence of "blotting" in biomedicine.
