Possible Reason |
Solution |
Inaccurate starting input |
In case of lower actual starting input, precise quantification by qPCR is recommended. |
Reaction mixture is not completely transferred out when pipetting. |
Transfer all reaction mixture from each step to a new tube when pipetting. |
Some magnetic beads are discarded during hybridization and bead purification |
Avoid too intense operation during the elution, and discard supernatant without losing any magnetic beads. |
