Wednesday 11 June

  • Morning:
    • Choon Kit, Hung:
      1. Gel electrophoresis for overnight digested products. Please refer to 10 June 2008 notebook


(Reminder: the ratio of loading dye to test sample is 1:5)
Result: +RBS 32 and 34 that were digested with XbaI and SpeI showed correct bands at 2kb. Control experiments (RBS 32 and 34 digested with EcoRI and PstI) also showed correct bands at 2kb.
+E7-1 PCR insert that was digested with XbaI and SpeI did not show any band, thus unsuccessful.

Insert 1 E7-0 PCR insert 16ul
Vector 2 empty plasmid vector(from RBS 32) 2ul
ligase buffer T4 ligase buffer 2ul
ligase enzyme T4 ligase 1ul
Total 21ul
