Fast Deprotect DNA Phosphoramidites
Fast Deprotect DMF-dG, iPrPAC-dG, PAC-dA, Ac-dC, and iBu-dC phosphoramidites are ideal for applications requiring mild deprotection to preserve the integrity of oligonucleotides containing sensitive dyes, labels, or other modifications, which may be unstable with prolonged exposure to strong alkaline conditions. Fast Deprotect phosphoramidites permit the removal of base protecting groups under mild or accelerated conditions without the need for special reagents.
