It's not silly at all...I have the service rep come and calibrate the spec
about 2 months ago (when I started hvaing problems). I also started using
brand new cuvettes then. Funny thing is that I can take the same cuvettes and
OD my maxi preps with the same machine in another lab!!
>>Guys, based on my OD260 I'm getting nanograms/ul of dsDNA. When I ran the
>>same amount on a gel, I got >2 micrograms/ul. Can you explain that?
>Silly question - when was the last time you (a) cleaned the cuvettes, (b)
>calibrated the spec?
