Highly Cross Linked Plain Resin
Our always-ready technical support and service teams go the extra step to be your most trusted resource. We're here for you.
Praesto Pure is an agarose-based chromatography media designed for large-scale biomolecule purification. It is the ideal base matrix for the production of affinity chromatography resins, and is available in three separate particle sizes - 45 µm, 65 µm and 90 µm - making it the ideal choice for high-resolution, intermediate and capture steps. Praesto Pure can also be directly used for gel filtration of larger biomolecules such as viruses and plasmids.
