Objective Ran Titration Analysis on KI-Colloid dialysis Ran Bradford Analysis on KI-Colloid dialysis Description Titration Added 3mL 1M HNO3 and 0.5mL KI solution to 10mL DI H2O Added 2 mL AgNO3 and swirl to complete precipitation Added 200 μL Ferric alum indicator Titrate with your NH4SCN solution Ran Bradford Analysis on KI-Colloid dialysis As expected, the Bradford analysis held a constant protein concentration Lysozyme is too big to pass through the 3500 MWCO so it was constant on one side KI is not expected to react with lysozyme so protein concentration was not affected Data Notes This area is for any observations or conclusions that you would like to note.
