Used primarily in chromatography for the purification and separation of proteins and peptides. It is particularly effective in cation exchange chromatography, where it binds positively charged molecules at low pH levels. Commonly applied in the biotechnology and pharmaceutical industries for protein purification processes. It is also utilized in laboratory research for isolating specific biomolecules from complex mixtures. The material is known for its high capacity and resolution, making it suitable for both analytical and preparative purposes. Additionally, it can be used in the initial stages of protein purification to remove contaminants and concentrate target proteins.
