A student wants to purchase some trypsin to use in a protein sequencing. Company A offers 200 I.U.'s of the enzyme with a specific activity of 405 I.U./mg at a price of $200. Company B offers 150 I.U.'s of the enzyme with a specific activity of 450 I.U./mg at the same price. Company C offers 405 I.U.'s of the enzyme with a specific activity of 200 I.U./mg at the same price. Which company(s) should you buy from?

 

I get Company A and/or Company C. Is that correct?
