Protein Calculator (MW and extinction coefficient)

Our protein calculator works as a protein MW calculator, extinction coefficient calculator, and protein molarity calculator. Upload your FASTA file and get the results for many protein sequences at the same time, without uploading your protein sequences one by one!

...

What can the Protein Calculator do for you?

...

Automatic MW and extinction coefficient calculations

Automatically calculate MW and ε from your protein sequences.

...

Multiple sequences processing

You can upload a FASTA file or paste your sequences one by one into the same calculation form.

...

Results export

No more copying and pasting your results! Automatically save them as a table with all the protein parameters you calculated.
