Protein Precipitation (PPT)
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. 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). 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. 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.
