You have a 5 mg/ml sample of GST (26 kDa). What is GST’s concentration in micromolar?

Answer: 192 micromolar

Explanation:

Molar mass of GST= 26000 g/mol

That means if one dissolve 26000 g of GST in 1 L ---> 1 Molar GST

5mg/mL GST = 5g/L

Therefore = 5/26000 =0.000192 M = 192 micromolar solution
