Use this simple tool to calculate, estimate, and predict the following features of a peptide based on its amino acid sequence:
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.
Some amino acids(Q, E(N-term), C, M, W, N, P, D) are less stable than others and are prone to side reactions. These reactions may occur even under our stringent production conditions. The final peptide yield is the sum of the product and the peptide that has undergone side reactions. Once the sum of the corresponding peaks in analytical HPLC reaches the requested purity, the peptide is shipped. While the total purity stays constant, the ratio of product and byproduct may change over time.
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.
