G'day all,

I would definitely say that the machine is unreliable, particularly at
measuring small amounts of DNA purified from gels (ie for probes or ligations).
One tech in the lab swears by the machine, and to be honest, she gets the most
reproducible results with the exception noted above.

We use the "low DNA concentration" buffer for best results at both the high end
of the range and low DNA amounts. WE use it for genomic DNA routinely without
too many problems, but it is the small gel fragments thatr I want to know with

Our machine was sent back for a circuit board upgrade and bulb replacement at
considerable cost (two-thirds of the original cost) but I have not reall y
noticed any difference.

I always check my purified fragments on mini-gel just to be sure.
