The effects is solution of the alkali‐metal chlorides on the gel‐like phase of DNA formed in the ultracentrifuge cell have been studied. The polycations, spermidine and spermine, also were shown to affect strongly the swelling pressure of the DNA gel, with evidence for the destabilization of DNA in very dilute spermine, below 10 −6 M , and for the collapse of DNA in both spermine and spermidine solutions above 10 −6 M .
