Hi allI'm looking for a way to calculate the protein concentration in a single crystal. So what I'm thinking is to use the Matthew's number to calculate how many molecules inside the crystal, then multiply that number by Avogadro's number to get moles then divide by volume of crystal. Is this approach correct?Thank you for your advice/suggestionHappy holidays! :)TeresaTeresa De la Mora-Rey Ph.D.Dept.
