NetMHCpan 2.8 Server

NetMHCpan server predicts binding of peptides to any known MHC molecule using artificial neural networks (ANNs). The method is trained on more than 150,000 quantitative binding data covering more than 150 different MHC molecules. Predictions can be made for HLA-A, B, C, E and G alleles, as well as for non-human primates, mouse, Cattle and pig. Further, the user can upload full length MHC protein sequences, and have the server predict MHC restricted peptides from any given protein of interest.

Version 2.8 has been retrained on extented data set including 10 prevalent HLA-C and 7 prevalent BoLA MHC-I molecules.

Predictions can be made for 8-14 mer peptides. Note, that all non 9mer predictions are made using approximations. Most HLA molecules have a strong preference for binding 9mers.

The prediction values are given in nM IC50 values and as %-Rank to a set of 200.000 random natural peptides. For alleles distant to the MHC molecules included in the training of the method, only the Rank score is provided.

The project is a collaboration between CBS, IMMI, and LIAI.

As of July 8th, the nomenclature for BoLA-I has been updated to follow IPD Release 1.3.

or submit a file containing a full length MHC protein sequence in FASTA format directly from your local disk:

Threshold for strong binder: % Rank  OR IC50 
Threshold for weak binder: % Rank  OR IC50 

Sort by affinity 

Include IC50 prediction value for all alleles (default is for white-listed alleles only)  

Save prediction to xls file

Data resources used to develop this server was obtained from

  • IEDB database.
    • Quantitative peptide binding data were obtained from the IEDB database.
  • IMGT/HLA database. Robinson J, Malik A, Parham P, Bodmer JG, Marsh SGE: IMGT/HLA - a sequence database for the human major histocompatibility complex. Tissue Antigens (2000), 55:280-287.
    • HLA protein sequences were obtained from the IMGT/HLA database (version 3.1.0).


Would you prefer to run NetMHCpan at your own site? NetMHCpan v. 2.8 is available as a stand-alone software package, with the same functionality as the service above. Ready-to-ship packages exist for the most common UNIX platforms. There is a download page for academic users; other users are requested to contact CBS Software Package Manager at
