I contacted Proteos in August 2019 to explore the expression of a protein from a parasite. The Proteos president and CSO recommended some parallel approaches, starting with DNA synthesis, and ending in transfection of HEK cells. The result is that we have enough highly purified protein to create monoclonal antibodies against it, all within four months of project initiation and at budget. While we could not know at the time whether or not the protein was well behaved (it was), the Proteos team did a fantastic job with strategic planning and execution, and met all of our expectations for timing and costs. I strongly recommend them for expression-know how and professionalism.

I called on Proteos when our lab was having trouble expressing recalcitrant protein. We did not have the means to switch to a eukaryotic system so rather than start from scratch we worked with Proteos to generate protein. They were very flexible and worked with us to find a cost-effective alternative, after which time we had protein in-hand! Their customer service was exemplary, and I will contact them again in the future if we run into more trouble. .

Proteos delivers protein. Conscientious and confidential handling of your important research projects to facilitate your science so you can answer the biological question, without becoming snagged on protein expression and purification issues. The Proteos team is friendly and enthusiastic and especially good at providing panels of mammalian expressed mAbs, Fc-fusions and other biologicals in quantities required with correct qualities (eg. Low endo) whether you need in vitro and/ or in vivo testing.

I chose Proteos on the recommendation of a colleague at the Van Andel Institute. I was told that the quality of their work and the purity of their product was exceptional. I have been very pleased with how responsive the team has been. They have answered every question as well as helped guide our project towards success. I had the pleasure of touring their facility and was struck with how the entire team took pride in their important work.

We have worked with Proteos for over a year, mainly for large scale (5-20 L) transient transfections for antibody production and purification. I really appreciate Proteos' quick turnaround from request to quotation (typically within 24-48 hours) as well as their expertise in protein purification. They are also willing to take on work with accelerated timelines and has met or delivered ahead of deadlines on all projects so far. The purity of proteins and quality of work is exceptional.
