Abstract
A new method for photosensitized polymerization of polyacrylamide gels was proposed. Photopolymerization of acrylamide/N,N′-methylenebisacrylamide (AM/Bis) was assisted with combination of catalyst ethylenediaminetetraacetic acid disodium salt dihydrate (EDTA) and photoinitiator riboflavin (RF). The prepared cross-linked AM/Bis + EDTA/RF gels were tested in electrophoretic SDS–PAGE system at high concentration of AM (20 wt%). The efficiency of these systems for electrophoretic separation of histones of human blood lymphocytes was demonstrated. In principle, such gels with small pores in the separation zone can offer advantages for resolution of proteins. The advantages of proposed method also include simple technique and possibility of gel preparation in a timely manner (for 10–15 min). However, in microporous gel systems some limitations in electroblotting technique could occur, which is particularly crucial for hydrophobic proteins.
期刊介绍：
The Protein Journal (formerly the Journal of Protein Chemistry) publishes original research work on all aspects of proteins and peptides. These include studies concerned with covalent or three-dimensional structure determination (X-ray, NMR, cryoEM, EPR/ESR, optical methods, etc.), computational aspects of protein structure and function, protein folding and misfolding, assembly, genetics, evolution, proteomics, molecular biology, protein engineering, protein nanotechnology, protein purification and analysis and peptide synthesis, as well as the elucidation and interpretation of the molecular bases of biological activities of proteins and peptides. We accept original research papers, reviews, mini-reviews, hypotheses, opinion papers, and letters to the editor.
