So, in my case, pH of the solution is adjusted to (pI + 1) or (pI - 1). I wonder if there is any difference for protein stability between two conditions, adjusted buffer pH is below pI or above pI.

More specifically pH is the negative logarithm (in base 10) of the molar concentration of H⁺. The pI (iso-electric point) is the pH at which the protein (or other molecule), overall has a net zero charge. As @Chris points out, the buffer you are using will change the pH the protein finds itself in.

Main Difference The main difference between Pi and Phi is that the Pi is a ratio of the circumference of a circle to its diameter and Phi is a letter in the Greek alphabet

The isoelectric point (pI) is the pH at which the charges of amino acid residues (C , D, E, H, K, R, Y) and the amino- and carboxy-terminus of the peptide chain 

By measuring the hydrogen-ion activity in water-based solutions, this sensor gets a pH reading. 2020-02-04 · The pH scale ranges from 0 to 14. A low pH value indicates acidity, a pH of 7 is neutral, and a high pH value indicates alkalinity.

In ion exchange chromatography, there are charged chemical groups on the resin and these can cause a protein to be retained on the resin if the protein is complementary (opposite charged) to the resin. If we set the amount of protonated acid, HA, to 1, then by the equation above, [A⁻] is equal to $10^{(pH - pK_a)}$ so the ratio is: $\qquad\large{\frac{[\text{HA}]}{[\text{HA}] + [\text{A}^-]} = \frac{1}{1 + 10^{(pH - pK_a)}}}$ We can use this ratio to determine the pI of a protein. Main Difference The main difference between Pi and Phi is that the Pi is a ratio of the circumference of a circle to its diameter and Phi is a letter in the Greek alphabet Below PI- protein is positively charged and it will bind to the negatively charged cation exchange resin, whereas above PI protein is negatively charged and will bind to the + charged groups of an At pH=pI is the pH in which the protein is most insoluble. The net charge is 0, but there are negative and positive groups which could be organized in clusters and if two molecules find each other Indeed, when the pH buffer is equal to the pI (isoelectric point), the protein has no charge. Consequently, the protein is not able to bind to an ion exchange column (anion and cation). Adjusting the pH below or above the protein pI induces a positive charge when pH < pI and a negative charge when pH > pI (Fig.1). Phi (Φ) and pi (Π) and Fibonacci numbers can be related in several ways: The Pi-Phi Product and its derivation through limits The product of phi and pi, 1.618033988… X 3.141592654…, or 5.083203692, is found in golden geometries: Golden Circle Golden Ellipse Circumference = p * Φ Area = p * Φ Ed Oberg and Jay A. Johnson […] The Federal government requires organizations to identify PII (Personally identifiable information) and PHI (Protected Health information) and handle them securely.
