General description
Cap 1 solution consists of n-methylimidazole, lutidine, and acetonitrile (ACN).
Application
Cap 1 is suitable for use after the phosphoramidite reaction/coupling step.
Biochem/physiol Actions
Cap 1 solution aborts chains bearing unreacted 5′hydroxyl groups due to failure of reaction with activated phosphoramidite (typically, 1 to 2% of growing oligonucleotide chains in each synthesis cycle). These unreacted 5′hydroxyl groups are capped with an acetyl group and thus rendered unreactive for subsequent synthesis steps.
