Hamilton* Protein Columns: PRP-3 and PRP-Infinity

PRP-3 columns are able to analyze protein purity quickly at both low and high pH extremes. A single peak on a chromatogram is no guarantee of protein purity. Howerver, when a single peak is found at both pH extremes, chances are that the protein is pure. The highly inert polymeric resin reduces non-specific binding and enhances protein recovery. 300 A pore size.
PRP-Infinity reverse phase columns simplify the separation of high molecular weight proteins. The non-porous resin produces a column capable of fast, high resolution results. The short separation time minimizes band broadening which keeps peaks narrow and detectability high.
