Determine isoelectric point of a peptide
WebDec 29, 2024 · Isoelectric point, also called the pI of the protein, is the pH at which the net charge of the protein is zero. Isoelectric point (pI): The pH at which the net charge on the protein is zero. For a protein with many basic amino acids, the pI will be high, while for an acidic protein the pI will be lower. How to Calculate Peptide Charge and ... WebIsoelectric point, also called the pI of the protein, is the pH at which the net charge of the protein is zero. Isoelectric focusing is a separation technique which separates peptides according to their isoelectric point, or how acidic and basic their residues are. A gel with a pH gradient is used as the medium.
