One can not always be sure if the beef salami is actually beef, or whether it has more to do with pig or horse. genbank If you want to find this out, must do so by using a gene isolation, genbank followed by PCR (Polymerase genbank Chain Reaction) and do gel electrophoresis. genbank And that made for even the price of the bio-chemical placement of Q11 by Jan Kolditz, who performed in the genetics laboratory of the Bernhard Striegel-Gymansiums in Memmingen the steps described himself.
Accompanying the students: Processed meat samples from a variety of foods. Among other things, white sausages should be investigated by local butchers, beef salami and meat burgers. The first task was to isolate the DNA from the samples. This is only possible when penipler compliance with the prescriptions. Several times the students had tiny volumes of clear, colorless solutions from a pipette into the other receptacle, always with the risk that a single mistake the entire job can destroy.
Subsequently, the DNA solutions were in the thermal cycler. There, the PCR occurs in billions of copies are made from the very few DNA molecules with which it is only possible genbank to obtain a visual evaluation. In the final step, these copies were stained and separated in gel electrophoresis. Only if the previously suspected animal was actually present in the food, there was a visible band in the UV-light.
Big surprises remained from this time. In the white sausage pork and beef were detected, as well as in ground beef burger. Only in the beef salami and pork was included in addition to beef, but this is also allowed by law as. Maybe the food scandals in recent times have made a difference anyway with the producers. For safety's genbank sake, there were on the way home but still a vegetarian ice.
