Excellent Customer Service

"...[Gator Bio] was extremely helpful, flexible and professional with [their] responses to our questions, and... allowed us to test their technology onsite which allowed us to make a vigorous comparison with the existing competitor BLI platform..."

Mauro
Research Scientist

Great results, fast turnaround. First instrument I'd buy as new faculty

"Gator Bio has manufactured a wonderful instrument in measuring (both kinetics and quantitatively) biomolecular binding events, more so than conventional SPR or FCS."

Zachary
Graduate Research Assistant

Jack of all trades for screening and quantitation

After comparing BLI providers we decided on Gator Bio due to their excellent data quality and very competitive price. Integrating the platform into our facility has allowed users to quickly screen potential candidates saving them considerable time."

Kelvin
Staff Scientist

Great product! Very user friendly and intuitive! Easy to operate and reliable

"The Gator Prime is very easy to operate, and much easier than the traditional SPR. Sample prep and running time for each assay were reduced by more than half. The system is also compatible with crude samples, which saved a lot of time and effort. "
