Fiberglass isoelectric point
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). However, pI is also used. For brevity, this article uses pI. The net charge on the molecule is … See more 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. The See more The terms isoelectric point (IEP) and point of zero charge (PZC) are often used interchangeably, although under certain circumstances, it may be productive to make the distinction.

Webisoelectric points ranging (pI) from 5 to 6 (Branoviciv et al, 1998). Wolf v (1959) reported that FVIII is optimally stable between a pH of 6.9 and 7.2 with large decreases in stability below pH 6 and above pH 8. This inherent instability could greatly complicate any purification process based upon isoelectric focusing (IEF) because the pI of FVIII WebJul 25, 2016 · The force dependence on solution pH reveals the protein isoelectric point, pI. At low pH, the proteins are positively charged, and are strongly attracted to a negatively charged surface. At the pI ...
