Many research applications require concentration of dilute protein solutions. Protein solutions may be concentrated by precipitation, chromatographic capture and elution, or by lyophilization.  A disadvantage of lyophilization is non-protein agents are concentrated along with the protein and these may interfere with subsequent downstream applications.
G-Biosciences offers a selection of protein concentration kits suitable for concentrating proteins for running gels, raising antibodies, protein purification, protein assays and other applications.  Proteins concentrated with these kits are suitable for the majority of downstream applications.

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 immobilizes any protein in a low salt buffer b..
Concentrator Solution is a novel liquid polymer for the rapid concentration of dilute protein solutions with zero loss, using dialysis.   Simply transfer your dilute protein solution to a dialysis bag or dialysis device*, such as our patented Tube-O-DIALYZER™ and dialyze against the con..
The OrgoSol-PROTEIN-Concentration™ kit precipitates protein with a proprietary solvent buffer, OrgoSol™. The OrgoSol™ buffer has been specifically developed for efficient precipitation of protein solutions with minimal disruption to the protein structure and therefore maintains the..
Tube-O-CONCENTRATOR™ is a versatile concentration device that utilizes a novel, water absorbing, liquid polymer and our patented Tube-O-DIALYZER™ for the rapid concentration of dilute protein solutions with zero protein loss.  The unique tube design of Tube-O-DIALYZER™ ensures..
Our Universal Protein Precipitation Agent, commonly known as UPPA™, has been specifically designed for the quantitative concentration of protein solutions as dilute as 1ng/ml into a small volume. Protein concentration and precipitation is not affected by the presence of detergents, chaotropics..
$0.00 provides an interactive version of this protocol where you can discover and share optimizations with the research community.    The UPPA-PROTEIN Concentrate™ kit uses our proprietary reagent UPPA™ (Universal Protein Precipitation Agent) to quantitatively concentr..
