http://isoelectric.org/theory.html WebNov 14, 2015 · 1 Introduction. In a titration curve, the isoelectric point (pI) is the value at which the overall net surface charge of a macromolecular polyprotic species equals zero.Protein pI values are amongst the most widely determined and widely reported quantities in all of biochemistry and proteomics. The pI is obtained as essentially …

WebThe isoelectric point (pI) of a peptide is the pH at which it has a net charge of zero. We can calculate the pI of each peptide fragment using the pK values of its constituent amino acids. The position of each fragment on an isoelectric focusing gel will depend on … WebTherefore, they will become cystines, which do not express any charge. Nevertheless, one can approximately calculate protein isoelectric point which is ± 0.5 of exact isoelectric point. The most critical moment during isoelectric point determination is usage of appropriate pK values. Unfortunately, there is no agreement in this matter. iphone red bar
