Project Update
Bottleneck
- Extreme low amount of ligated product
- Low adapter ligation efficiency
Improvements
- Start of with high amount of input DNA (500ng & 1ug)
- Increase the amount of adapter and increase annealing time
Quantification of Jurkat PCR Product
Qubit: 48.4ng/ul
Library Prep with new Jurkat PCR product
- Concentration:48.4ng/ul
- BP:100BP
- setup: 1ug, 500ng and -ve control
