The Protein Calculator (previously hosted at calculates parameters based on a one-dimensional protein sequence.

This is a web application, so please go to

The protein calculator does:

  • Molecular weight-based calculations
  • Estimated charge-based calculations
  • Estimated UV absorbtion-based calculations
  • Atom and residue counting
  • Solvent content calculations for X-ray crystallography

Additional documention will be added later.
