Co-M8 (Cobalt Ion) (ID# 9923)
DNA
Cobalt Ion (Co2+)
Other
187±3.7 µM (reported value)
50mM HEPES, 100mM NaCl, 0.025% Tween-20, pH
7.5
Room Temperature°C
Heated to 95 C for 10 minutes, cooled on ice for 10 minutes, placed at room temperature for 10 minutes
Specific against other counter-selected metal ions (Mn2+,Cu2+,Ca2+,Al3+, Ba2+,Cd2+,Ni2+,Zn2+,Ce3+,Pb2+,Cr3+,Fe3+ and Hg2+) except Hg2+ which non-specifically binds to thymine bases.
Magnetically tunable. Effective binding is achieved only when a magnetic field of 6T or greater is applied.
