چکیده
1. Protein Separation Methods The following is a quick review of some common methods used for protein separation: SDS-PAGE (SDS-polyacrylamide gel electrophoresis) separates proteins mainly on the basis of molecular weight as opposed to charge (which is ‘swamped out’ by the excess of protein-bound SDS) or folding (proteins are largely denatured in SDS). In the ideal picture, the distance migrated by the protein in a given time is inversely related to the logarithm of its molecular weight:

Proteins Separation and Purification Methods with Focus on Chromatography: a Review Study
Before describing the structure and mechanism of action of a protein, it must first be subject to purification procedure. Protein purification is a set of processes in which one or a small number of proteins are purified from a complex compound that may be a complete cell, tissue, or organism. Understanding the functions, structural properties, and interactions of the protein are directly re...
متن کاملProtein and Lactose Separation by Modified Ultrafiltration Membrane using Layer by Layer Technique
Layer-by-Layer (LbL) is a method which can be used for nanoscale coating and surface functionalization of a material. LbL technique mainly uses the electrostatic attracting between charged materials (polyelectrolytes, nanoparticles, etc.) and an oppositely charged surface. In this study, protein separation (BSA) from lactose solution was carried out using the LbL self-assembly method, which was...
