Hi Netters,

I have a problem with  some oligos I made on our synthesizer, and I hope
maybe someone can help:

The machine usually automatically removes the 5' trityl group before
delivering the oligo in ammonia solution.  I then deprotect by heating
overnight at 55C before ethanol precipitating the oligo.

Unfortunately, the machine was set wrongly this time, so that the trityl
group was left ON.  I discovered this before precipitating the oligo but
after deprotecting at 55C.  The question is, what, if anything, should I do
to detritylate my oligos?

Many thanks fo ryour help....
