We've been long-time users of IDT DNA oligos in all their variants. Recently, we ventured into CRISPR technology and came to rely on IDT sgRNAs for their dependable performance and super-fast delivery. The combination of high quality, improved stability, and quick turnaround helps keep our gene editing projects moving forward without delays. Even after several freeze-thaw cycles, IDT sgRNAs remain stable and continue to perform reliably.
