Question: I wish to create a data set for MHC class I or Class II binders (IC50<500) or non-binders (IC50>5000) for any organism. With the current version I am not able to do so. Earlier, there was a clear option of Perform Advanced Query, which was clear to create a data set.
Answer: Thank you for your inquiry. The advanced search feature is still available under the "Specialized search" menu of the IEDB homepage. Please follow the "MHC assay details" link. In the Assay filter box on the left-hand side of the page you can expand the Measurement Details line to expose text fields for entering minimum and maximum values in nanomolar (nM).
