TESTIMONIALS

Testimonials

Quality Forensic Toxicology
Our extraction time has decreased significantly and our recovery is much better than with our previous enzyme. Ordering has been a breeze – the last product we used often had shortages and left us in a bind. That has never happened with Kura! Additionally, you could not ask for a friendlier team of people to deal with. We love the Kura product and the Kura folks!
 
Janine De King, Quality Forensic Toxicology.
 
Premier Biotech
The B-One enzyme performance met all of our expectations. That combined with the price and top-quality performance from our sales rep, John Drohen, made moving to Kura an easy transition.
 
Garrett Cook, Premier Biotech.
 
Rize Laboratory

Kura's B-One enzyme has streamlined our benchtop process - it continues to provide benefits to our toxicology department on a daily basis. Fewer mixing steps, faster digestion, and cleaner data provide better reliability and free up more time for testing and implementing additional process improvements. Technical guidance, customer service, and shipping speeds have been similarly impressive.

 

Eric Lyons,  Rize Laboratory.

 

Uppsala Universitet

My laboratory has worked with Kura’s ASPC and BGTurbo enzymes for several years and enjoyed the positive scientific interactions with Kura’s Finden team. The robustness, broad substrate hydrolysis properties and purity of their enzymes were critical for the development of our Chemical Biology tools for metabolomics and microbiome metabolism analysis.

 

Daniel Globisch, Ph.D., Uppsala University

 

Kashi Clinical Laboratories

Our laboratory chose BGTurbo Kura Biotech Enzyme due to Its Purity, Stability, Easy storage, Non-consuming Worktime (oven time), and very easy to purchase with the good customer service team behind the scene.

 

Khashayar Kashi, Kashi Clinical Labs

 

Westox Labs
Our confidence in our results is everything, and what your product allows us to do is have that as well as a faster process within our laboratory. We’ve seen improvements in many areas including our workflow and data output.
 
K. Outland, Westox.
 
Progressive Diagnostics
BGTurbo was a blessing for us. It is a very easy to order product and there is a friendly relationship with the people in the company. Many of the problems we had eliminated with BGTurbo including precipitates that arise from our prior product. It really enables the laboratory to function smoothly and helps with fast processing data. As a company we strive to provide accurate and quality data to our customers and BGTurbo enables us to achieve that.
 
Chamila Rupasinghe Ph.D., Progressive Diagnostics LLC.
 
American Toxicology
The B-One enzyme has been working great, it has made our sample prep so much easier!
 
Angie Garcia, American Toxicology.
