ExPASy logo Compute pI/Mw tool


Compute pI/Mw is a tool which allows the computation of the theoretical pI (isoelectric point) and Mw (molecular weight) for a list of Swiss-Prot and/or TrEMBL entries or for a user entered sequence [reference].


Documentation is available.

Compute pI/Mw for Swiss-Prot/TrEMBL entries or a user-entered sequence

Please enter one or more Swiss-Prot protein identifiers (ID) (e.g. ALBU_HUMAN) or Swiss-Prot/TrEMBL accession numbers (AC) (e.g. P04406), separated by spaces, tabs or newlines. Alternatively, enter a protein sequence in single letter code. The theoretical pI and Mw (molecular weight) will then be computed.

Or upload a file from your computer, containing one Swiss-Prot/TrEMBL ID/AC per line:
