The Art of Phosphitylation

New biologically active entities rely heavily on advancements in phosphorylation methods. Learn why phosphitylation with highly reactive PIII reagents, which use tunable protecting groups, offers significant synthetic advantages.

 

Is Your Single-Use Solution Ready for Oligonucleotide API in Solution?

New, high-performance fluid handling systems and technologies are in demand for biomanufacturing, but these new modalities come with risks, such as synthetic DNA contamination from DNA or RNA fragments. An alternative to traditional polyethylene bags is offering cell and gene therapy manufacturers a solution to contamination concerns.

 

Thermal Stability of Phosphoramidites In Oligonucleotide Synthesis

In drug design, thermal stability is a critical factor that can shape the success of innovative treatments. Beyond impacting drug efficacy, thermal instability poses risks to production safety and business continuity. Our phosphoramidite study provides essential insights to mitigate these challenges in drug synthesis.
