What’s unique about the ProTrap XG?

Protein precipitation is a proven technique and is remarkably effective when performed properly. The challenge is in reproducibility- especially in low microgram protein amounts, when a pellet may not be visible. The ProTrap XG eliminates the possibility that you will accidentally disturb your protein pellet and can improve throughput.

Do you have published research results?

Our co-founder, Alan Doucette, and his team at Dalhousie University regularly publish research posters and papers featuring the ProTrap XG. You can view these at any time in our Posters and Publications online library.

What type of samples can be used in the ProTrap XG?

Protein samples that are clarified and that can be precipitated using acetone have been successfully processed using the ProTrap. Our team is actively working on sample processing protocols to provide users with complex samples input parameters for successful precipitation. Low molecular weight proteins (<5kDa) tend not to precipitate well. We are currently exploring new strategies to successfully process these smaller proteins.

How does the ProTrap XG clean samples?

The ProTrap XG uses protein precipitation, aggregating the protein in a solvent. Anything soluble in the solvent is washed away when the solvent is removed during a centrifugation step. The precipitated protein is retained by the integrated membrane, while solvent-soluble contaminants are flushed through. Our protocols are based on methods published by our Chief Scientist, Alan Doucette and other researchers in peer-reviewed research articles.
