Enzyme concentrations are often characterized by 'units' of activity per volume.
One enzyme we will be using, Sbfl, is supplied in a concentration of 10,000 units/mL
a. How many are there in 1 uL?
b. How much volume would you need for 20 units?
c. We have 500 units total, how much volume is that?
(a) Given concentration is 10,000 units/mL
That means 1 mL contains 10,000 units
1 uL = 10-6 mL contains (10,000 units*10-6 mL) / 1 mL = 10-2 units
(b) Given concentration is 10,000 units/mL
That means 10,000 units requires 1 mL
20 units require (20 units*1 mL) / 10,000 units = 0.002 mL
(c) Given concentration is 10,000 units/mL
That means 10,000 units requires 1 mL
500 units require (500 units*1 mL) / 10,000 units = 0.05 mL
