  • The DNA was extracted from the gel slices using the Zymoclean Gel DNA Recovery Kit
Sample 260 280 260/280 ng/μL
H2B 0.006 0.004 1.463 6.384
LOV 0.011 0.004 2.769 11.492

  • ---Karmella 21:34, 15 November 2012 (EST): Next step - ligation & transformation

Refer to this page for a full description: http://openwetware.org/wiki/Haynes:Assembly101

  • Use 20 ng of vector for each ligation = 5 μL pSB1A3
  • Use 2x moles of H2B insert, relative to vector: xμL H2B insert = 2 * 410 bp H2B / 2000 bp pSB1A3 * 20 ng pSB1A3 / 6.384 ng/μL H2B = 1.28 μL H2B
  • Use 2x moles of LOV insert, relative to vector: xμL LOV insert = 2 * 461 bp LOV / 2000 bp pSB1A3 * 20 ng pSB1A3 / 11.492 ng/μL LOV = 0.8 μL LOV
  H2B LOV Negative Control
Insert DNA (2x mol vector) 1.0 μL 1.0 0
Vector DNA (50 ng) 5.0 5.0 5.0
2x Roche Rapid Ligation buffer 7.0 7.0 7.0
New England Biolabs T4 ligase 1.0 1.0 1.0
dH2O 0 0 1.0
TOTAL 14.0 14.0 14.0
Mix the reaction(s) thoroughly by flicking the tube.
Incubate at room temperature for 10 minutes.

Proceed directly to Transformation. See http://openwetware.org/wiki/Haynes:Assembly101
