Number of amino acid residues: | 1-character: | 3-character: | Molecular weight: |
---|---|---|---|
Peptide sequence input
1 sequence input
You can enter your polypeptide sequence (amino terminal → carboxyl terminal) in the box under "Sequence", the input format can be 1 or 3 characters of amino acids, or a combination of both.
2 Selection of peptide N/C terminal modifications
The aminoterminal modifications were acetylation, biotin labeling and pyroglutamate.。
Result analysis
1 Molecular weight
The molecular weight of the polypeptide can be calculated quickly by inputting the target sequence。
2 Isoelectric point
The isoelectric point is the PH of the target polypeptide at zero net charge, calculated according to the authoritative Lehninger Principles of Biochemistry.
