Deprotection: Use Ammonium Hydroxide and deprotect as required by nucleobases. If AMA is used, a small amount of a non-fluorescent impurity will be formed. To eliminate this impurity, first deprotect with ammonium hydroxide for 30 minutes at room temperature, add an equal volume of 40% methylamine and then complete the deprotection as required by the nucleobases - e.g. 10 minutes at 65°C or 2 hours at room temperature for standard bases
