Using the BDB database as a virtual and comprehensive control in background, the MimoSearch tool in the SAROTUP suite is designed to check if any submitted peptide has also been gained by other groups with various targets. If any, such peptide may be a target-unrelated peptide rather than a true target binder, because the chance of obtaining an identical peptide from a library having millions or billions of different peptides with completely different targets is extremely small. Here we go! (Download standalone tools on the Download page.)
