Praesto Jetted SP35 is an agarose-based, strong acid cation exchange resin designed for biomolecule purification, including proteins, peptides and oligonucleotides. It is manufactured using 'Jetting' - a new, patented method that produces agarose beads with a very narrow particle size distribution.
Purolite is the first agarose resin provider to produce process-scale volumes of uniform particle size beads.
