Tailored assays for better drug discovery

Implementing the appropriate biological assay is pivotal in determining the success of your drug discovery program. Our flexible approach to method development, validation, and implementation guarantees the delivery of the right method for your needs.

With our proven track record working with over fifty clients, you can confidently depend on us to reproduce complex literature methods, enhance them to meet pharmaceutical research standards, optimize existing protocols, and run off-the-shelf assays. The outcome is a test that is both accurate and robust: an assay you can trust.


"The level of engagement, commitment, and dedication to the program that the entire team at Paraza has shown is impressive. The success to date is a reflection of that hard work, and we sincerely appreciate it."

Top-tier expertise integrated into your team

Our approach is built on the depth and breadth of our team’s scientific expertise.

Over 70% of department members hold PhDs, and our multidisciplinary and collaborative ecosystem covers a wide range of expertise across the fields of oncology, metabolic disease, immunology/inflammation, central nervous system (CNS) disease, microbiology, and virology.

We engage with you throughout the process — from ideation, assay design, and implementation to data interpretation and troubleshooting — to help you achieve your goals.
