Restek Resprep 96-well protein precipitation (PPT) plates

Restek’s line of Resprep sample preparation products has expanded to include 96-well protein precipitation (PPT) plates. The Resprep PPT3 96-well plates offer efficient protein removal with built-in, drip-free membrane and three-way versatility for filtration, so the user can easily prepare serum, plasma and other biological samples.

The plates offer greater than 99% protein removal and drip-free, in-well protein precipitation for a minimum of 24 h — with no fear of backflushing or contamination. A dual-layer membrane with different porosities in each layer prohibits clogging, speeds up filtration and, using the company’s recommended solvent-first method, streamlines sample preparation even further.

The 2 mL deep wells are suitable for mixing by vortex or pipette, and the 96-well plates can be used to increase throughput in general filtration applications. The versatile plates are compatible with all common filtration devices: vacuum manifold, positive pressure manifold and centrifugation.
