The optimal primer for cDNA synthesis depends on the desired downstream application.
| Downstream Applications | Primers | Goal |
|---|---|---|
| qPCR quantitation | Random Primer Mix (NEB #S1330S) Typical recommendation: 6 µM final |
Even coverage |
| General cDNA synthesis | Oligo d(T)23VN (NEB #S1327S) Typical recommendation: 5 µM final |
Full-length cDNA synthesis |
| Random Primer Mix or Random Primer Typical recommendation: 6 µM final |
Even coverage | |
| Gene-specific Primer Typical recommendation: 0.5 µM final (Range: 0.1 - 1 µM) |
Target-specific cDNA |
