combination of an anionic polyelectrolyte with a cationic surfactant,
it has been shown that DNA, which is an anionic polyelectrolyte,
could be quantitatively precipitated with cationic surfactant in
49
water, using hexadecyltrimethylammmonium chloride (CTMA), by
an ion-exchange reaction 50–51 (see Fig. 8.5). The resulting DNA-lipid
