Tasks for September 10

  • To run UV-Vis of Bradford-BSA and Bradford-Lysozyme solutions
  • To determine the purity of the protein solutions

Preparing the solutions for UV-Vis

Refer to Dr. Fox's Lab notebook for full details <br.>

  1. To prepare 50 mL of a standard saline solution (0.9 wt-%):
    • (50mL)×0.9%=0.45 g of NaCl need to be added
  2. To prepare 50 mL of a 50 mM Tris 50 mM NaCl solution:
    • (50×10-3mol/L)×(0.050L)×(121.14g/mol)=0.3030g of Tris buffer
    • (50×10-3mol/L)×(0.050L)×(58.44g/mol)=0.1461g of NaCl
