- Isoelectric point - Wikipedia
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) [1]
- 25. 3: Isoelectric Points and Electrophoresis - Chemistry LibreTexts
The isoelectric point, pI, is the pH of an aqueous solution of an amino acid (or peptide) at which the molecules on average have no net charge In other words, the positively charged groups are exactly balanced by the negatively charged groups
- What is Isoelectric Point - Creative Proteomics
In essence, the isoelectric point refers to the pH value at which the surface charge of the particle is zero Upon reaching the isoelectric point, various physical properties of ampholytic electrolytes, such as solubility, viscosity, and osmotic pressure, minimize, a phenomenon particularly evident in protein solutions
- What Are Isoelectric Points and Why Are They Important?
What Exactly Is an Isoelectric Point? The isoelectric point (pI) is a specific pH value where a molecule carries no net electrical charge At this pH, the total positive charges on the molecule precisely balance its total negative charges
- Isoelectric Point - GeeksforGeeks
A protein's isoelectric point (pI) is the pH at which the protein carries no net electrical charge It is a characteristic property of a protein and is determined by the overall composition of its constituent amino acids and their respective pI values
- ISOELECTRIC Definition Meaning - Merriam-Webster
When the brain is starved of blood flow (ischemia) and oxygen (anoxia), the patient faints in a fraction of a minute and his or her electroencephalogram, or EEG, becomes isoelectric —in other words, flat
- IPC - ISOELECTRIC POINT CALCULATION OF PROTEINS AND PEPTIDES
Isoelectric point, the pH at which a particular molecule carries no net electrical charge, is an critical parameter for many analytical biochemistry and proteomics techniques, especially for 2D gel electrophoresis (2D-PAGE), capillary isoelectric focusing (cIEF), X-ray crystallography and liquid chromatography–mass spectrometry (LC-MS)
