Effects of additives on A, C, G, and T-tailinga.
| Additives (concentration) | A-tailing | C-tailing | G-tailing | T-tailing | note |
|---|---|---|---|---|---|
| GMP (10 mM) | no effect | ++ | − | − | induce continuous C-tailing |
| GDP (5 mM) | − | ++ | − | − | induce continuous C-tailing |
| dG (40% sat.) | no effect | ++ | no effect | no effect | |
| CDP (2 mM) | no effect | + | + | no effect | induce continuous G-tailing |
| dC (200 mM) | − | − | +++ | no effect | |
| rA (40% sat.) | no effect | + | no effect | +++ | |
| dA (40% sat.) | no effect | − | no effect | +++ |
a‘+’, positive effect increasing the tailing index by less than 1; ‘++’, moderate positive effect; ‘+++’ marked positive effect; ‘−’ negative effect.
