Scientist Spotlight

Kevin Van Cott, Ph.D.

Kevin Van Cott, Ph.D., heads the Prolytix high-resolution mass spectrometry (HRMS) lab. A global expert in host cell protein and biotherapeutics characterization, Dr. Van Cott discusses his approach and what brought him to Prolytix.


Prolytix stands out as a service provider of choice due to an impressive depth of blood and protein knowledge and a higher touch service model versus larger players.


Senior program manager, biotech company focused on immune deficiency disorders

The scientific knowledge and rigor Prolytix brought to the table was excellent, and turnaround time was fantastic compared to the large, global CROs. Prolytix clearly understood the scope of our request, their written reports were clear and exceeded our expectations for GMP scientific reports.


CEO, biotech company focused on development of immuno-oncology and infectious diseases therapeutics

The Prolytix team was timely, precise, concise, and helpful in developing the best immunoassay for our needs. We successfully improved upon the published finding and also gained certainty about species specificity. It is essential to have good assays to clearly understand biology. I am very grateful to have had the opportunity to work with this team and hope to work with you again in the near future.
