Protein Purification
Cell ExpressionProcedure1. The correct concentration for dissolving LB Broth Media into water is 25g per liter of water. - For the 1L LB Broth solution, 25g of LB Broth Media were dissolved into 1L of water - For the 25mL LB Broth solution, 0.625g of LB Broth Media were dissolved into 25mL of water The solution are placed in the autoclave at 121 degrees C for an hour. 2. In order to prepare the ampicilin solution, 500mg of Ampicilin Sodium Salt were dissolved into 5mL of sterilized water. This solution was prepared in a sterilized eppendorf tube using sterile equipment. 3. Once the solutions cool, 25uL of the ampicilin solution is added to each of the 25ml flasks and 1mL is added to each of the 1L flasks 4. The 25mL flasks were inoculated with K31c Asc Hb (BL21DE3) cells and placed on the shaking incubator at 37C and 225rpm overnight | |
