Prepare RNAseq library for sequencing

  • Continue with lab note on 7/8/11
  • Samples: PC1, PC2, GFP+, GFP-, E9.5, E11.5, E13.5m, E13.5f
  • 75ul sheared DNA store at 0.5ml non-stick tube over the weekend
  • Use NEB master mix kit for Library prep

End repair

Reaction 
sheared DNA           75ul
Master mix buffer     10ul
Enzyme mix             5ul
H2O                   10ul
Total                100ul
20C for 30min
Purification with AMPure beads
# 150ul beads to 100ul reaction (kapa lib prep kit suggested), mix 10 times, R.T for 8min
# Place on magnetic stand for 5min
# Remove sup., wash with 180ul fresh made 80% EtOH twice
# Air-dry for 15min, re-suspend with 32ul Qiagen EB, mix 10 times, RT 2min, magnetic stand 2min
# Transfer 30ul DNA from beads
Sample Concentration ng/ul
GFP+ 0.35 ug/mL
GFP- 0.24 ug/mL
E9.5 0.39 ug/mL
E11.5 1.29 ug/mL
E13.5m 0.54 ug/mL
E13.5f 2.27 ug/mL

A tailing

Reaction 
End-repaired DNA      30ul
Master mix buffer      5ul
Enzyme mix             3ul
H2O                   12ul
Total                 50ul
37C for 30min
Purification with AMPure beads
# 90ul beads to 50ul reaction, mix 10 times, R.T for 8min
# Place on magnetic stand for 5min
# Remove sup., wash with 180ul fresh made 80% EtOH twice
# Air-dry for 15min, re-suspend with 20ul Qiagen EB, mix 10 times, RT 2min, magnetic stand 2min
# Transfer 18ul DNA from beads, 1ul left in tube for Qubit measurement

Adapter ligation

  • 30uM Y-adapter made by Alice few weeks ago
  • 0.08ul for sample 1,3,4,5,7 and 0.4ul for 2,6,8
  • 50ul total with 10ul buffer and 5ul Quick T4 ligase
