Porvair Sciences has published video showing how to use a solid-state filter microplate to remove interfering proteins from serum, plasma or even whole blood samples prior to analysis by Liquid Chromatography/Mass Spectrometry (LC/MS).
Biological samples commonly contain proteins that interfere with downstream applications. The Porvair Sciences Protein Precipitation Plate (P3) plate uses the CRASH method, in which the protein is denatured with acetronitrile and the flocculant filtered out, allowing 96 samples to be handled at one time.
Based on the MicroLute format, but without the chromatographic sorbent, protein ‘crashes’ out of solution and precipitates directly in each well when acetonitrile is added, solving common problems associated with the CRASH technique of protein
clean-up. The novel dual frit, hydrophobically treated matrix used by the P3 plate means that there is no ‘wetting out’ and leakage of sample before the application of vacuum.
