: How sensitive are these labels?  Could they be used in gel shift
: experiments?  Also, how stable are they?  One bad thing about 32P is that
: you probe is useless after a couple weeks.

More questions:
Are the oligos stable for PCR? If so, will the biotin hang on long enough
for detection or purification via one of the avidin-biotin methods? Thanks.
