The person concerned doesn't have a way of monitoring A260 of washings from an oligo dT column directly (the monitor is broken and the lab has no money to fix it), and would rather not have to take aliqots to a spec to read A260. She has tried oligo dT paper, but is really after something that will provide a greater final quantity of clean PolyA+ RNA. I've suggested the (Pharmacia?) kit in which the oligo dT is coupled to magnetic beads, but this is an expensive kit and my friends lab isn't rich. Are there any (relatively cheap), simple protocols out there that will give large amounts (>25ug) of PolyA+ RNA. Please pass any hints/suggestions/protocols on to me and I'll pass them on to my friend. (I'll be quite interested in the answers myself, anyway!) Thanking you all in advance, ******************************************************************************** Jeremy Weinman Plant Microbe Interaction group Research School of Biological Sciences Australian National University Email: jjw@rsbs0.anu.edu.oz Phone: 61 6 2495051 Fax: 61 6 2490754 Snail: PO Box 475, Canberra, ACT 2601, AUSTRALIA ********************************************************************************
