Matsuo, Kimiko published the artcileThe effects of polyamines on the melting of poly(inosinic acid) plus poly(cytidylic acid) complex in solution, Synthetic Route of 10517-44-9, the publication is Bulletin of the Chemical Society of Japan (1966), 39(2), 347-52, database is CAplus and MEDLINE.
The thermal transition profile (melting profile) of the double-helical complex of poly(inosinic acid) and poly(cytidylic acid), poly (I + C), into random coils in solution was examined by observation of the absorbance at 248 m¦Ì. Increased cation concentrations raised the transition temperature (Tm) and made the transition more rapidly reversible. CH3NH3+, Na+, NH4+, and Mg++ were increasingly effective in that order. Diamines of the type +H3N-(CH2)n-NH3+ also raised Tm, the most effective being that with n = 3. Spermidine was even more effective, and spermine the most effective compound tested. Actinomycin D had little effect on Tm. Poly-
