The TriAltus Bioscience CL7/Im7 purification system has helped us combat solubility and purification issues with our protein of interest. We have tried various other systems and constructs to produce our protein of interest, none of which have compared to the results we have seen with this system. It is easy to use, from cloning to purification, and the team at TriAltus is very knowledgeable if any questions come up along the way. Thanks TriAltus!

The cost per item is amazing. I’ve reused the resin multiple times and haven’t seen any loss of binding. Furthermore, using an FPLC column, I have the ability to purify a protein in a couple of hours. The usability is great. Using CL7 we were able to purify a protein that we’ve had trouble with in the past.
