 One of the central points of Rheinberger’s analysis is that the in-vitro system was never designed to do this task. Its original purpose was to study protein synthesis in cancer cells. In addition to unraveling the genetic code and the mechanisms of protein synthesis, it was later used for various other purposes in biochemistry and cell biology (for example, for studying the transport of proteins across endoplasmic reticulum and mitochondrial membranes). The system was thus not even confined to a single discipline, in fact, it to some extent lead to a re-organization of scientific disciplines. Furthermore, the system was also fused with other experimental system or it bifurcated into different systems. Experimental systems, like model organisms are at least as important as focal points that organize research as theories.
