There are no kits, because 90% of the time this technique doesn't work....
I am fed up with it. I worked on it and my hair is all white.
I think it's primarily LUCK. yES flame me if you want, but I can point to
100 people who this technique hasn't worked for for everyone that you
point it worked for..... Complaining aside.
I use Perkin Elmer's GeneAmp kit. Basically I use the ragents and don't
follow any of the protocol. I use Superscrip II (GIBCO) for RT to get a
more efficient reaction. I do everything in triplicates and let my Rt
reacion go for 2 hrs.
My problem is that I get beautiful gels and can reamlify Beautifully BUT
when I do northerns-> Nada. Zip. Zilch.... They all show up positive in
the control and the test condition...
This is where I think the LUCK comes from.. You have to do enough to get
one or two to work for you. You may get lucky and get one the first time
you do it or have horrible luck and do 50 and not get one...
Hey Paul Why not write about this in Trends in Biological Sciences....
Tell'em shahram is suicidal.. :)
