The Column-PROTEIN-Concentrate™ Kit has been specifically developed for concentration of those proteins that cannot be concentrated either by precipitation or other techniques. The kit is based on a proprietary Protein Binding Resin that binds and immobilises any protein in a low salt buffer between pH 2 to 12. The binding capacity is ~0,5 mg protein/ml Protein Binding Resin.

The immobilised protein is spin-eluted in a small volume of specifically formulated elution buffer, giving several fold effective concentration. The method is gentle and protects protein from denaturation during the concentration process. The Column-PROTEIN-Concentrate™ Kit maintains and protects the biological activity of proteins and allows for ~100% recovery.

This kit is suitable for concentration of a total of 4 mg protein in either single or multiple procedures. For concentration of larger than 5 mg protein, a custom made kit may be ordered. The kit is supplied with a proprietary spin column; the column may be regenerated and reused once.
