How to use
  • Copy or type amino acid sequence of a protein, choose necessary items in "options" and push button "Calculate!"
  • Brutto formula and length of the protein are calculated alwais (independently of items you choose)
  • for calculation of molecular weigth of isotop content protein it is nessesary to mark isotopes in "options" (one or more)
  • You can learn more about error of calculations, calculation algotithm and other from menu on left side of the page.
