Desalting is a critical step in processing samples that have been isolated in the presence of salts and other small molecules. Resin-based desalting is performed by allowing the small molecules to freely enter the resin pore and be retarded in their flow through the packed resin bed while the high molecular weight molecules like proteins in the sample are excluded from the resin and rapidly exit the column. The exclusion limit of the resin is 7kD (Proteins)
The spin column and plate (96-well, and 384-well) method eliminates cumbersome column preparation or equilibration, allowing multiple-sample processing in less than 10 minutes. Samples containing as low as 20 μg per mL of proteins can be processed with ≥ 95% retention of salts and other small molecules (less than 1,000 Da)
