Amplification of BioBricks

Miniprep of BioBricks

  • Miniprep was performed using Qiagen kit and eluted in 35 µl ddH2O.
  • From 500 µl of liquid culture, a glycerol stock was prepared as described in Preparing glycerol stocks.

Result

  • DNA concentration was determined using nanovue.

The fragments of plasmids pSB4K5 and pSB1C3 show the expected pattern.

=> BioBrick backbone was cut and gel isolated.

NEB3 buffer (10x) 5
Enzymes (XbaI and PstI) 1.5 each
ddH2O 4.5
  • Incubation for 1 h at 37°C

Result

  • The restriction mix was loaded onto a 1% agarose gel using 6 µl gene ruler marker.
Fig. 2.1: Restriction results of 06-05. l1:2log, l2: P1 (pSB4K5),l3:2log, l4-5:amplified F1 for Backbone (pSB6A1), l6-7:amplified fragment 2 for Backbone (lacZ),l8:2log, l9: P3 (pSB13)

The fragments show the expected pattern.

=> LacZ insert were cut and gel isolated.

  • Purification was performed with Qiagen Nucleotide removal Kit and eluted in 38.5 µl ddH2O

Result

2.5 µl were measured with the Nanovue. The measurement proved the failure of miniprep.

, l1-2: lacz & pSB1AT,l3:2log ladder
=> lacZ was cut out


=>The band was too high on gel and discarded, because we cannot be sure if it really is lacZ or the backbone of the lacZ plasmid.
