Lambda phage lysis device

Lysozyme and holin production are driven by pBad, and antiholin is driven by PconC5.

K112019 (Lambda Lysis Device) was inserted in the vector K112950 and K112809 was insertedin pSB1A2. They were introduced into the MC1061 strain by transformation, and then picked 5 colonies for each device. We grew these cultures to saturation at 37 degrees Celsius in LB media, and then split into eight 1 mL aliquots. A range of concentrations of arabinose was added to these aliquots, with a starting concentration of 1.3E-3 M and the next 6 samples recieving a four-fold dilution of the previous sample, and an equal volume of water added to the last aliquot. The cultures were then incubated at 37 degrees again for 3.5 hours, and the absorbance at 600nm was measured with a Tecan Xfluor4 Safire2 in a Corning Inc. Costar 3603 plate. The data plotted on a log scale is shown below.

Data from adding arabinose at midlog. Concentrations used at each data point from left to right are 0, 2.44E-07, 9.77E-07, 3.91E-06, 1.56E-05, 6.25E-05, 2.50E-04, and 1.00E-03 M

A parallel experiment was performed by taking the same saturated culture before induction with arabinose, diluting 100-fold, growing to mid-log(starting OD .22), before inducing with arabinose as above. The data plotted on a log scale is shown below.

Data from adding arabinose at midlog. Concentrations used at each data point from left to right are 0, 2.44E-07, 9.77E-07, 3.91E-06, 1.56E-05, 6.25E-05, 2.50E-04, and 1.00E-03 M
