CEO, Gliknik Inc.

ExcellGene’s expertise and troubleshooting were pivotal in advancing our multi-specific therapeutic protein through CHO cell line development. Their commitment to quality, timely delivery, and clear communication ensured a seamless collaboration. Highly recommended!

Luigi Colombo

COO, EPOK Therapeutics Inc.

For an academic vaccine developer like me, it is of utmost importance to build our research program with the support of a biotech company with which we have built a high level of confidence and trust. Communication has to be easy and transparent, and the delivery of our product has to be in purity and quantity as needed, so that the timing for starting a clinical trial matches our plans. This is exactly the experience I have with ExcellGene. In addition to it, as a science-driven company, they bring innovative and creative solutions to complex problems.
