June 6 2008

Sebastian, John and Roxanne

Prepared 1L of semi-solid media following the procedure found on OpenWetWare.

-10g peptone (substituted for tryptone)
-10g Agar
-10g NaCl
-5g Yeast Extract

Stored media in fridge.

Christa, Munima, Roxanne, and Sebastian

Prepared 1L of liquid media following the procedure found on OpenWetWare.

-10g peptone (substituted for tryptone)
-10g NaCl
-5g Yeast Extract

Poured 36 culture test tubes, and the remainder was left in a 1L Erlenmeyer flask. Stored both in fridge.

Christa

Made an inventory of iGEM 2007 parts in Wieden -80 freezer inventory.xls

Roxanne

Defrosted the -20 freezer in the teaching lab for iGEM use (with a little help from my friends!)


June 11 2008

Sebastian, Munima, Roxanne, Christa

Poured 8 minimal media (labeled control - with blue sharpie) plates and 14 amp plates (labeled amp - with red sharpie) stored in the 4 C fridge. Amp concentration is always 50ug/mL.


June 16 2008

Nathan Puhl, Munima, Christa, Sebastian, Roxanne

Plated cheZ knockout strain from glycerol on LB + amp and Plain LB to assess viability and antibiotic resistance at 37 C overnight.

Transformed supercompetent cells with basic biobrick vector pSB1A7 (ampicillin resistance)

 -50 uL of cells, 0.85 uL 2-mercaptoethanol, 1 uL of plasmid dissolved with 15 uL of ddH2O
 -30 min on ice
 -45 s at 42 C
 -2 min on ice
 -Add 0.9 mL of LB shaker incubate at 225 RPM and 37 C


June 17 2008

Munima, Christa, Nathan Puhl

Checked plates

 -cheZ knockout strain viable on LB, no growth on LB + amp - Good
 -Only one colony from transformation, not very good efficiency, don't know why because too many possibilities, most       
   likely amount of DNA due to inability to quantify plasmid from iGEM plates
 -Subcultured colony in liquid LB + amp
 -Plate 200 uL on LB + amp at 37 C overnight


June 18 2008

Munima, Christa, Alix, Nathan Puhl

Made glycerol stock of pSB1A7 transformed E. coli

Extracted plasmid from transformed E. coli using the Eppendorf FastPlasmid minikit and stored 4 aliquots of 25 uL in the -20 C freezer.


June 19 2008

Nathan Puhl, Alix, Munima, Christa, Roxanne

Ran plasmids on 1% agarose gel with High range ladder

June 24 2008

Nathan Puhl, Alix

Streaked BBa_I13522 (TetR repressed GFP) onto LB + amp from last year's glycerol stock.


June 25, 2008

Nathan Puhl, Sebastian, Alix

Subcultured I13522 into liquid LB + amp for plasmid mini prep
