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.
