The stability of polypurine tetraplexes in the presence of mono- and divalent cations.
As with other guanine-rich sequences, poly[d(GGA)], poly[d(GA)] and poly[d(GAA)] probably form four-stranded or tetraplex structures. Thermal denaturation profiles were measured for these polymers at pH8 in the presence of Na+, NH4+, K+, Cs+, Mg2+, Ca2+ and Ba2+. For poly[d(GA)], Na+, NH4+, K+ stabi...
