See what they’re saying.

Our customers and colleagues have a lot to say about NovaFlour™ Technology!

“I conjugated Thy1 to NovaBlue 610 and it is working beautifully!”


Cara Hrusch

Senior Scientist – AbbVie

“The NovaFluors all show more restricted excitation/emission profiles than traditional fluorophores in the same range, and would make for good replacements in our panels. 

The NB610, NB660 and NY570 are also much “cleaner” than the respective versions from BD:  BB630, BB660 and BYG584.”


Oliver Burton, Ph.D.

Staff Scientist – Babraham Institute

“The 40-c panel is already best in class … I think the approach to not go for the brightest but for the best resolution or least background is key for that”


Florian Ebner, Ph.D.

Advanced Flow Cytometry Expert – Boehringer Ingelheim

“Going away from the tandem paradigm cleans up the annoyances with designing panels in terms of better resolution and brighter markers…

This is a stepping stone in the progress of Cytometry. Now that we have these tools, we might be able to get away with not getting a UV line that’s super expensive and still get the same number of really good markers.”


David Leclerc

Technical Director – Cytometry and Antibody Core (CAT) Facility, University of Chicago

“Bringing this kind of technology into improving panel design is really exciting and we’re looking forward to more fluorochromes coming out of Phitonex” 


Rui Gardner

Core Head – Flow Cytometry Core Facility, Memorial Sloan Kettering Cancer Center

“Successfully tested Phitonex conjugation kit with NovaBlue 660 and 610 dyes. Highly recommended to all cytometrist[s]! Bright Fluorochromes, less spillover, easy conjugation procedure. Many thanks to Mike Stadnisky and Seddon Thomas for shipping it quickly.”


Abhisek Koladiya

Cytometrist and Data Scientist – Institute of Hematology and Blood Transfusion, Prague

“The best addition to flow cytometry in the last 10 years.  This product allows you to stack new markers in already crowded flow cytometry panels.  The dyes are bright with very low background.”(SelectScience Review)


Hugues Allard-Chamard, MD PhD FRCPC

Visiting Scientist – Ragon Institute of MGH, MIT and Harvard

“I tried out the NovaBlock, and the reduction in non-specific binding is really fantastic. I don’t see anything comparable with BioLegend’s monocyte blocker or various CD16/32-blocking antibodies.”
