1. What color change occurs when proteins combine with Coomassie dye under acidic conditions?

Use the provided material to answer questions 2-4.

Using BSA concentrations of 0 mcg/mL, 1 mcg/mL, 3 mcg/mL, 4 mcg/mL, and 5 mcg/mL you get the following absorptions: 0.02, 0.12, 0.32, 0.42, 0.52.

With your sample you dilute it 1:5 and get an absorbance of 0.15.

2. What is the standard curve equation for this BSA standard?
