Protein Calculator. Uses CGI so you'll be fine. It's not designed for prettiness anyway.

Protein calculator

Molecular mass, ɛ280 and concentration (requires A280)

You must answer me these questions three, ere the answer you may see

Alternatively
choose a protein from the list:
Your protein could be here! Email me if you want it in the pull-down list.

AND
What is the A280 reading: and dilution factor: ? e.g. '100' not '1:100'
