Top Questions

What’s unique about the ProTrap XG?

Protein precipitation is remarkably effective when performed properly, though challenging to pursue in a reproducible fashion. The ProTrap XG eliminates complex pipetting, and greatly improves throughput. What’s more, the versatility of the device, with its integrated SPE Cartridge, allows you to adapt the ProTrap XG to any number of established protocols in your lab.

Do you have published research results?

Our Chief Scientist, Alan Doucette, Research Associate, Jessica Nickerson along with other members of the Proteoform Scientific R&D team regularly publish posters and papers on the ProTrap XG. You can view these any time in our Science section.

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

The ProTrap XG is designed to purify all types of proteins, from simple to complex mixtures.

How does the ProTrap XG clean samples?

We use a combination of solvent precipitation (Filtration Cartridge) and solid phase extraction (SPE Cartridge) and follow optimized, peer-reviewed protocols to ensure the highest level of purity, yield and throughput.

Sample Prep Questions

What type of yield can I expect with the ProTrap XG?

Users typically see greater than 95% recovery of proteins.

What level of purity can I expect with the ProTrap XG?

The ProTrap XG is capable of removing over 99.8% of sodium dodecyl sulfate (SDS). It can also eliminate salts as well as other buffer components.

Does the ProTrap XG do peptide cleanup?

Our team is currently exploring new cleanup strategies in low molecular weight (<5 kDa) proteins and peptides through precipitation. However, the reversed phase SPE Cartridge and associated protocols are ideally suited for peptide recovery and cleanup.

What’s the volume of sample that the ProTrap XG can handle?

The Filtration Cartridge holds up to 500 microliters. But keep in mind, this volume includes the organic solvent used for precipitation, which is why we suggest up to 100 microliters of sample solution.

How much protein can the ProTrap XG prepare?

Having demonstrated exceptionally high recovery down to sub-microgram quantities, the device can accommodate up to 100 microliters of protein, or up to 1 mg protein.

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

The ProTrap XG is designed to purify all types of proteins, from simple to complex mixtures.
