I don't use NIH/3T3 cells, but I used Qiagen RNeasy Kit for different
cell lines. I usually took my 6-well plates straight from the incubator
to ice, sucked off the media, washed once with PBS and lysed the still
adherent cells the lysis buffer of the Qiagen RNeasy Kit (use as much
volume as will finally fit onto the column) . Then I scraped off the
lysate with a cell-scraper and followed the usual protocol. The RNA
worked fine in RT-PCR analysis.
