The results are recorded on a log - log graph , with the hybridization counts on
the vertical axis and the amount of purified DNA fixed onto the filter on the
horizontal axis . For details , see Materials and Methods . 89 90 biol 10 8 8 6 6 4 .

This novel and inexpensive approach to microporous filter modification entails
soaking filters in an aqueous solution of a cationic polymer such as
polyethyleneimine ( PEI ) for 2 h at room temperature and then allowing the filters
to air dry ...
