      We don't seem to have this problem at all and we use the same
wash procedure quite a lot of the time. However, we dont hybridise
using Denhardts, salmon sperm DNA, polyA etc......we just use 6XSSC, 1%
SDS, 500µg/ml Heparin sulphate (standard grade i.e ordinary). The
heparin sulphate replaces all that messy Denhardts etc and works
