Single-end solexa sequencing library
Materials
use previously captured samples capture reaction setup can be found under LabNotes 8-15-09 and 8-16-09 samples to be used: D3(6&7 subsets of NA12878), DF6-9-9, foreskin, ips(PGP1-ips), Cvi(CV-ips), CVf(CV-fibroblast)
Procedure
Reagent setup: (Pair-end sequencing library construction) Solexa_1 adaptor and Solexa_2_PE adaptor will be used for PCR at the last step use these primers: Solexa_PCR_PE_loH & Solexa_PCR_upH (single-end sequencing library construction) Solexa_1 adaptor and Solexa_2 adaptor will be used for PCR at the last step use these primers: Solexa_PCR_up Solexa_PCR_lo
