I use Nytran (neutral-charge) membrane from S&S with the following
50% formamide/5x SSPE/2% casein (Hammerstein grade) /1% SDS/100-500 ug/ml
ss carrier DNA at 42oC. I do many Northerns that are hyb'd with various
random primed and end labeled probes, and these hyb. conditions work
consistently well for me.
Hope this helps!
