5.14 Humulin

Key Points:
1. In 5.13b we saw the making of transgenic cells using a virus capsule and a bacterial cell.
2. A culture of this bacteria will be put in a fermenter and this culture will need to be provided with nutrient, temperature and pH and the gases which are in the chamber. By creating the optimal temperature, the population will increase and the bacteria manufacture more and more insulin.
3. The product will then be removed and then purified. There are many purifications needed to make it safe for humans. Called downstream processing. Humulin.
