AND Gate Notebook

Week 1: Research and Planning (08/06/09 - 12/06/09)



Day 1 Monday (08/06/09)

  • Researching the Registry for Biobricks
    • Focus on T7 parts (I712074, I719005, K113011, K113012, J34814, K103021, R0085, R0180, R0182, Z0251 and Z0252) for possible use in our project.
    • Other BioBricks identified for other sub-projects include R0062, J40001, J37015 and R0063



Day 2 Tuesday (09/06/09)

  • Researching literature for T7 promoter strength and degradation rate
    • Useful article - Imburgio, D., Rong, M., Ma, K., and W. T. McAllister. (2000) "Studies of Promoter Recognition and Start Site Selection by T7 RNA Polymerase Using a Comprehensive Collection of Promoter Variants" Biochemistry.39:10419-10430



Day 3 Wednesday (10/06/09)

  • Researching literature for parameters of LuxR, LacO, TetO and cIO
    • Useful article - Braff, J. C., Conboy, C. C., and D.E. Endy. Promoter Characterization Experiments. (found at openwetware.org/images/3/30/PromoterChar_Report_Revised.doc)
  • Identified plasmids that potential Biobricks were on and prepared for rescue.
    • Also indentified LVA tags and any other anomalies on selected Biobricks.



Day 4 Thursday (11/06/09)

  • PoPs to LacZ alpha repoter identified (E0435) and potenially useful Input Output sensor (pSB1A10)
    • Other possible reporters include LacZ alpha fragments and Enhanced stable YFP.
  • Possibility of intentional SNP generated within T7 to alter promoter strength was deemed unworkable in the scale of project.
