iPS library construction

The five libraries were pooled together as the following ratio (second PCR-amplification was not performed,
these are amplified capture product)
pooled all the subsets together using the ratio: 
1-100%(Jan09 1+2+3); 2-50%(Jan09 4+5DS); 3-73%(Jan09 6+7); 4-73%(Mar09 2+3, Jan09 5SS)
pooled all the subsets together using the ratio: 1-100%; 2-50%; 3-73%; 4-72%

Qiaquick column purification

MmeI digestion

DNA                  23ul     
10x NEB buffer 4     4ul      
1mM SAM              6ul     
2U/ul MmeI           8ul     
MinElute purification and elute in 100ul EB.
  • Sent out the five libraries to Harvard for Covaris shearing
  • Received five sheared samples from Billy, ~400ng in ~80ul each
  • Use the NEBNext DNA Sample Prep Master Mix Set I kit for library construction.
  • Use the Y-adaptor for ligation.

  • Purify with Qiaquick columns, eluted with 30ul EB.
  • Perform size selection on 20ul DNA with 2% size selection gel, extract the ~100bp bands.

Ligation

  • Mix 20ul A_adaptor_b (100uM), 20ul A_adaptor_t (100uM), 5ul 10x Taq buffer, 55ul H2O.
  • 94C 3min -> ramp to 20C at 0.1C/sec -> 4C hold.
  • Assuming we have 100ng of 80bp fragments, and the Adaptor:Insert ratio is 50:1, we need ~100pmole of the adaptors.
  • Include a positive control.
