Protein Precipitation (PPT)

Protein Precipitation (PPT)


Resprep PPT3 96-Well Plates

  • Polypropylene protein precipitation (PPT) 96-well plates offer highly efficient >99% protein removal.
  • Minimum 24-hour drip-free feature for easy in-well protein precipitation—no fear of backflushing or contamination.
  • Built-in dual-layer membrane with different porosities in each layer prohibits clogging and speeds filtration.
  • Solvent-first method streamlines sample preparation.
  • 2.0 mL deep well—suitable for mixing by vortex or pipette.
  • 3-way versatility for filtration—compatible with all common devices:
    • Vacuum manifold
    • Positive pressure manifold
    • Centrifugation
  • Can also be used to increase throughput in general filtration applications.

Well Plates

  • Polypropylene plates with round-bottom wells reduce liquid retention; conical bottom provides optimal recovery of reagents.
  • Nunc shared wall technology allows increased well volume for optimum storage capacity and improved mixing.
  • Round well shape is ideal for applications that require vortexing.
  • Ideal for sample collection, storage, sampling, and combinatorial chemistry and library applications.
  • Fits most autosampler compartments.
  • All microplates manufactured by Nunc meet the recommendation of American National Standards Institute (ANSI) (ANSI/SBS 1-2004).

Universal Sealing Mats

  • Protect contents and prevent carryover with preslit cap mats.
  • Chemically resistant, silicone mats are excellent for compound storage to -80 °C.
  • Preslit mats pierceable by autosampler needle, pipette tip, or probe.
  • Universal mat for sealing 0.45, 1.3, and 2.0 mL plates.

Resprep VM-96 Vacuum Manifold for 96-Well Plates

  • Heavy-duty, stainless steel and aluminum body stays in place and does not slide like lighter models.
  • Viewing window allows easy observation of plate height and drip rate.
  • Durable O-ring and gaskets resist solvent damage and provide leak-free seals time after time.
  • Precision-manufactured parts assemble quickly and easily, with perfect alignment of well plate and collection plate.
  • Customize plate height to your exact requirements; precision height adaptor and five shims in a range of thicknesses allow easy, accurate configuration.
  • Works with any manufacturer’s well plates and collection plates for solid phase extraction (SPE), supported liquid extraction (SLE), protein precipitation (PPT), and filtration.
