I use AgarAce from Promega to extract large (5-10 kb) PCR fragments from
agarose. This works alright, but could be better. I would like to try some
of the protocols suggested in this thread, but I am doing this in high
quantity (upwards of 70-80 fragments at a time)--it would be a bit daunting
to prepare individual tubes each time (I am in a 96-well block now.) Any
ideas for high- throughput (and still high-yield) isolations?
Thanks,
Jen
