preparing gene transfer assay

Following Juliens advices and references (....), we founded that b. Subtilis was a good candidate for our gene transfer assay. Even more since we had already strains: there are 3 strains in IGEM2011 glycerol stocks:

BSPY79: wild type. SB513: Kan resistant. (stored as S10) SB473: CM resistant. (stroed as S11)

Baback is worried that BSPY79 is contaminated. To ckeck it and to obtain a non contaminated new glycerol stock;

Analytical digest of pMG.004 miniprep from 18/7/12

Expected:

  • 2020 bp backbone pST1A2
  • 1940 bp insert BBa_I716462

5uL digest with XbaI and PstI 3xMinipreps C1, C2, C3

  • Bad result, what is the problem? It's as though it is 1/2 digested but the size is too small (would be 4kb)

Re-doing analytical digest of pMG.004

  • Only of C1 miniprep from 18/7/12
