Therapeutic Antibody Sequences

Updated report: Sequences from 745 antibodies and fusion proteins

Updated 15th February 2023:

In the following links you will find two spreadsheets containing antibody sequences for 745 therapeutic antibodies & fusion proteins.

We’ve created them as a resource for the scientific community – we hope that it will help you to design new and improved therapeutics at a faster rate.

Our spreadsheet includes antibody name, heavy and light chain sequences, target and isotype information. We’ve also separated each sequence into a column per amino acid for easier comparison of all mutations.

You don’t need to submit any data to download the spreadsheets: we just ask that you make your colleagues aware of ichorbio and the spreadsheet if you find it useful. We are looking to add more information to the spreadsheet soon – including Fc silencing data to each sequence so please check back frequently. If you have any requests please email

ichorbio supplies research grade biosimilars to 188 therapeutic antibodies – links to all are included in the spreadsheets.
