Isoelectric focusing is also the first step in 2-D gel polyacrylamide gel … Visa mer The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I). … Visa mer The isoelectric points (IEP) of metal oxide ceramics are used extensively in material science in various aqueous processing steps (synthesis, modification, etc.). In the absence of … Visa mer • Henderson-Hasselbalch equation • Isoelectric focusing • Zeta potential Visa mer For an amino acid with only one amine and one carboxyl group, the pI can be calculated from the mean of the pKas of this molecule. Visa mer A number of algorithms for estimating isoelectric points of peptides and proteins have been developed. Most of them use Henderson–Hasselbalch equation with different pK values. … Visa mer The terms isoelectric point (IEP) and point of zero charge (PZC) are often used interchangeably, although under certain circumstances, it … Visa mer • Nelson DL, Cox MM (2004).
