TA-4FF 70µm is a customized gel filtration medium made from 4% agarose that has been emulsified, rinsed, crosslinked several times, and sieved, and is used for the separation and purification or detection of biomolecules such as polysaccharides, nucleic acids, and viruses, and the medium is also often used as a substrate for affinity, hydrophobic, and ion exchange chromatography.
Features:
- Resistant to autoclaving at 121°C, suitable for application in large-scale separation and purification
- Higher degree of cross-linking than TA- CL 4B, more stable physicochemical properties
- Fast flow rate, shorten process time
