Peptides bind to charged stationary phases (anion or cation exchangers) and are eluted by changing the pH or ionic strength of the mobile phase.Methods to protein and peptide extraction from microalgae This method is particularly useful for purifying peptides with distinct charge properties.
* Size-Exclusion Chromatography (SEC): Also known as gel filtration chromatography, SEC separates peptides based on their molecular size. Larger molecules elute faster as they cannot enter the pores of the stationary phase, while smaller molecules that can permeate the pores elute later. This technique is often used for desalting or separating peptides from very large proteins.
Solid-phase extraction (SPE) is a versatile technique frequently used as a sample preparation step, either before or as part of the purification process. SPE utilizes a solid sorbent material to selectively retain peptides while allowing other components to pass through, or vice versa.Recent progress of food‐derived bioactive peptides ... - IADNS It is highly effective for concentrating peptides from dilute solutions, removing interfering substances, and preparing samples for downstream analysis such as Liquid Chromatography-Mass Spectrometry (LC-MS/MS).
