  • Selim Sheikh:
    • Designed set of sequencing primers (using Vector NTI Advance 10 http://www.invitrogen.com/site/us/en/home/LINNEA-Online-Guides/LINNEA-Communities/Vector-NTI-Community/Sequence-analysis-and-data-management-software-for-PCs.html) to be used in PCR of lambda DNA to amplify the region bounded by the restriction sites M.NgoMIV and AvrII:
        • product of length 4362
        • contains region of the molecule from 20040 to 24401
        • Tm = 78.4 C TaOpt: 58.7 C GC: 45.5
        • sense primer: GCCGGCGATGCCAGTGCATCAGCTGCTCAG <----------primer name: stfU L
        • length: 30 Tm = 78.2 C GC = 66.7
        • antisense primer: CCTAGGCAGGTCATTGGCAACAGTG <-----------primer name: stfU R
        • length: 25 Tm = 62.5 C GC = 56.0


  • David Ouyang
    • We are currently having some difficulties extracting the DNA from the binder for this year. We have tried multiple transformations with positive controls (the + grew, the biobricks did not). Today we tried a PCR of the extracted DNA against a positive control.
