Considering having a custom peptide synthesized? Analyze it here first.

Use this simple tool to calculate, estimate, and predict the following features of a peptide based on its amino acid sequence:

  • Peptide physical-chemical properties, including charge-pH map, pI, hydrophobicity, and mass
  • Ease of peptide synthesis and purification, including relative speed of delivery
  • Peptide compatibility with SRM/MRM quantitative mass spectrometry workflows

Peptide Analyzing Tool

Type or paste the sequence of a peptide and click “Analyze”. The tool can auto-detect most formats of single-letter and three-letter amino acid sequences (e.g., EQKLISEEDL, Glu-Gln-Lys-Leu-Ile-Ser-Glu-Glu-Asp-Leu), or you can specify which format you input. Multiple sequences can be analyzed at a time by entering or pasting each sequence on a separate line. Multiple sequences must be in the same format.

Note: This analysis tool does not support any peptide modifications and sequences shorter than 4 amino acids. The quality of this analysis may be significantly affected if the input sequence is longer than 25 amino acids. To assess and optimize peptides for antigenicity and other properties relating to antibody production, use the Antigen Profiler Peptide Tool.
