Our Customers
Dedicated experts in research and synthesis of nucleobases
Starting in 2005, Nublocks was founded in California to provide high quality nucleosides and phosphoramidites for drug development research. Initially begging with a focused offering nucleoside triphosphate conversion for biology research groups for their nucleic acid-based drug discovery. As the research demands evolve, so have we. NuBlocks have since expanded its portfolio to offering over 1000 different nucleobase analogs. We create the buliding blocks for your mRNA solution so you can stay focused on effective drug discovery and delivery. This service has allowed researchers to fine-tune their nucleic acid building block properties for the best stability, enzymatic activity, and medical efficiency. Our nucleoside phosphates have accelerated the drug discovery for both pharmaceuticals and university research groups. NuBlocks promises to never compromise on quality, delivery time and price.
