TA-4B is a gel filtration resin made of 4% agarose through emulsification, rinsing and sieving, used for the separation and purification or detection of biomolecules such as polysaccharides, nucleic acids, and viruses, and are often used as a base for affinity, hydrophobicity, and ion-exchange chromatography media. The gel structure of TA-4B is fixed by hydrogen bonding, and the substrate is relatively soft and poor in compression resistance. It is not resistant to autoclaving.
