Frequently Asked Technical Question

QUESTION: What is the procedure for deprotecting with AMA?

RESPONSE:The AMA reagent is a 50:50 mixture of aqueous Ammonium

hydroxide and aqueous MethylAmine. With AMA the cleavage of the

oligonucleotide from the support is accomplished in 5 minutes at room

temperature. The deprotection step is carried out at 65°C for a

further 5 minutes. Deprotection can also be carried out at lower

temperatures as shown in Table 1. In all cases, no base modification

has been observed.
