How can we convert 0.1 mg/ml of BSA protein into M(mole) unit?

29 November 2015 1 5K Report

I have prepared 0.1 mg/mL BSA in distilled water. What can we convert 0.1 mg/mL into Molar unit?

Hi,

The mass of BSA is ~66430 Da. Use the unit conversion of 1 Da = ~1 g/mol. Since 0.1 mg/ml is equivalent to 0.1 g/L, then the molar concentration of 0.1 mg/ml is calculated by (0.1 g/L) / (66430 g/mol) or ~1.5 E-6 mol/L.

Best,

Collin
