Exp.1 PCR on the pooled captured DNA

I still have some capturing reactions from 11-21-07, 11-26-07, 12-03-07 left. I decided to pool the reactions from the same templates togethers, and do PCR to make more Solexa sequencing library. The reason is that, based on the quantification experiment did yesterday, there are still not enough number of circularized molecules per target.

                              one reaction        8 reactions
          Template:           5~10ul                  each

Exp.2 Probe prep. for the CES22k set on two new libraries

Emily resynthesized two libraries for the CES22k set.

  1. CES22k 01783910053 (received Nov. 2007, same sequences as the above library) 100nM
  2. CES22k 10783810008 (received Nov. 2007, contains Solexa amplification adaptors) 100nM
