ISOLUTE® PLD+ plates and columns deliver cleaner extracts than other phospholipid removal products, meaning lower detection limits can be achieved. In the example below, signal-to-noise when using ISOLUTE® PLD+ was more than double when compared with competitor products (figure 1, below), leading to an immediate enhancement in sensitivity.

More than 99 % of phospholipids are removed as the sample passes through the multifunctional sorbent bed, leaving clean, purified extracts for analysis. Removing phospholipids also improves analytical column lifetime, preventing the build-up of phospholipids over multiple injections, and maintaining analyte sensitivity over extended analytical runs.
Using a simple solvent crash/filtration based procedure, proteins and phospholipids are simultaneously removed from plasma and other blood based samples while high, reproducible analyte recoveries are maintained. The optimised frit arrangement acts as a depth filter, efficiently trapping precipitated proteins, without blocking or plugging.
ISOLUTE® PLD+ plates and 'tabless' columns have excellent flow characteristics, and do not plug or block during use. They can be processed easily using either positive pressure or vacuum based systems, and are compatible with most automated liquid handlers. For method development, or variable sample numbers, use tabless columns in special racks on Biotage® Pressure+ 96, Extrahera and VacMaster-96 systems.
