PCR investigation
There was nothing left at the crime scene but a few traces of blood. Surveillance cameras and eyewitness testimonies have led to several people being suspected. Which of them is the culprit? In this lab exercise, we will find out: from samples collected by forensic scientists, we will use polymerase chain reaction (PCR) to amplify unique DNA patterns and analyse them using gel electrophoresis. At the same time, we will try out some new exercises for the biology exam. [...]
Examination of proteins usable in cancer diagnostics by electrophoresis
Proteins can be engineered into highly specific and sensitive recognition molecules and enzymes for substances of medical diagnostic interest, due to their complex structure and interaction patterns. These genetically engineered proteins are produced in and isolated from bacteria. In this laboratory exercise, the production of proteins is followed by gel electrophoresis, giving the opportunity to gain practical experience in some new areas of biology [...]
