Empirical Proteotypic Peptide Explorer:

This rose plot enables visualization of proteotypic peptides. Each colored rose petal corresponds to a peptide and is bounded by thin gray petals, which represent tryptic cut sites. The radial magnitude of each peptide corresponds to the number of publications which report it.

Hover over a rose petal with your mouse to see the peptide. Click on a rose petal to see the species specificity of that peptide and add it to your cart.

4 ESP = ESP Predictor. Fusaro VA, et al. Nat Botechnol 2009; 27(2): 190-198. doi

5 CONSeQ = CONSeQuence. Eyers CE, et al. Mol Cell Proteomics 2011; 10(11). doi

Underline: Peptide occurs within the first 20 amino acids from the start of the protein. Use caution as the protein may contain a cleaved signaling sequence.

Strike-through: Peptide is present in a protein from another allergen species and is thus nonspecific.
