Week 11: 08/4/08 - 08/7/08

08/4/08

  • Plasmid digestion for:
J23100-B0030-C0040-B1006 (E-S) R0040 (E-X)
  • Gel run/cut/gel extraction.
  • Ligation: J23100-B0030-C0040-B1006-R0040. We incubated ligation at 16°C overnight.
  • We had 5 plates to screen with colony PCR:
    • B0030-C0051-B0030-C0079-B1006-R0051-B0030-C0062-B1006-R0062-B0030-E1010-B1006 (that we call "a")
    • B0030-C0061-B1006-R0062-B0030-E0040-B1006 (that we call "b")
    • B0030-C0078-B1006-R0079-B0030-E0040-B1006 (that we call "c")
    • B0030-C0061-B0030-C0079-B1006-R0079-B0030-E0040-B1006 (that we call "d")
    • J23100-B0030-C0012-B1006-R0010
  • Last week J23100-B0030-C0012-B1006-R0010 colony PCR gave a bad result. For this reason, we decided to perform colony PCR only for:
    • B0030-C0061-B1006-R0062-B0030-E0040-B1006 (7 colonies)
    • J23100-B0030-C0012-B1006-R0010 (6 colonies)
Marker 1Kb, blank, J23100-B0030-C0012-B1006-R0010 (6 colonies), B0030-C0061-B1006-R0062-B0030-E0040-B1006 (7 colonies)
  • Gel result:
    • B0030-C0061-B1006-R0062-B0030-E0040-B1006 (1st colony, but it was not pure. We decided to prepare single colonies plate for it)
    • J23100-B0030-C0012-B1006-R0010 (2nd colony)

08/4/08

  • We transformed J23100-B0030-C0040-B1006-R0040 overnight ligation. We plated transformed bacteria and incubated plate at 37°C overnight.
  • We infected 9 ml of LB + Amp with 30 µl of C0062, Lig.12, Lig.22, Lig.30, Lig.27(2nd col), B0030-C0061-B1006-R0062-B0030-E0040-B1006 (1st col) (see "Parts" section for our nomenclature).
  • Single colonies plates for:
    • B0030-C0061-B1006-R0062-B0030-E0040-B1006 ("Lig.b")
    • B0030-C0078-B1006-R0079-B0030-E0040-B1006 ("Lig.c")
    • B0030-C0061-B0030-C0079-B1006-R0079-B0030-E0040-B1006 ("Lig.d")

08/5/08

  • Glycerol stocks/miniprep for C0062, Lig.12, Lig.22, Lig.30, Lig.27(2nd col), B0030-C0061-B1006-R0062-B0030-E0040-B1006(1).
  • We sent C0062, Lig.12, Lig.22 and Lig.30 purified plasmids to Primm for sequencing: all these parts contain BBa_C0062.
  • We transformed/plated J23100-B0030-C0040-B1006-R0040 overnight ligation.
  • Colony PCR for a (7 colonies), Lig.b(single colonies)(6 colonies), Lig.c(single colonies)(6 colonies), Lig.d(single colonies)(6 colonies).
Marker 1Kb, blank, Lig.a (7 colonies), Lig.b (6 colonies), Marker 1Kb, Lig.c (6 colonies), Lig.d (6 colonies)
  • Gel results were not so clear: the length of some fragments was not expected and there were some contaminants. Maybe those parts were too long for our PCR reaction. We decided to grow 9 ml cultures for some of those colonies, to extract plasmids, to cut them and to check their length in a new run. We chose:
    • B0030-C0051-B0030-C0079-B1006-R0051-B0030-C0062-B1006-R0062-B0030-E1010-B1006 (1, 4, 6, 7)
    • B0030-C0061-B1006-R0062-B0030-E0040-B1006 (no colony was chosen: we already had them and this run didn't show any 100% pure colony)
    • B0030-C0078-B1006-R0079-B0030-E0040-B1006 (5)
    • B0030-C0061-B0030-C0079-B1006-R0079-B0030-E0040-B1006 (2)

08/6/08

  • Single colonies plate for J23100-B0030-C0040-B1006-R0040, because where were too many bacteria on its plate.
  • Glycerol stocks/miniprep for:
    • B0030-C0051-B0030-C0079-B1006-R0051-B0030-C0062-B1006-R0062-B0030-E1010-B1006(1)

    • B0030-C0051-B0030-C0079-B1006-R0051-B0030-C0062-B1006-R0062-B0030-E1010-B1006(6)
