  • Type IIS Assembly, PCR: H2B-LOV+his



Type IIS Assembly, PCR: LOV-H2B+his

  1. H2B = 378 bp, 1A3/H2B fwd + H2B/LOV rev (Template: H2B-GFP from Addgene)
  2. LOV = 429 bp, LOV fwd + LOV+his/1A3 rev (Template: LOV from Addgene); note: reverse primer adds a 6-his tag and TAA stop (21 bp)
  3. pSB1A3 = ~2000, gg0001 v2 + gg0002 v2
  • Be sure to use the H2B and LOV primers ordered on 2/4/2003. The names are redundant with a previous version.

PCR

  • 95°C, 3 min.
  • [95°C, 30 sec.; 57°C, 30 sec.; 72°C, 1 min.] x35
  • 72°C, 3 min.
  • 4°C, ∞
Reagent Volume Expected:
1. H2B = 378
2. LOV = 450
3, 4. pSB1A3 = ~2000

Purification

  • Clean with Zymo DNA c&c; elute w/ 20 μL dH2O
  • Measure [DNA]
Sample OD 260 260/280 ng/μL
1. H2B 0.04 1.667 40.4
2. LOV+his 0.019 1.562 18.6
3. pSB1A3 0.069 1.754 69.4
4. pSB1A3 0.085 1.817 85.5


Dilutions: to final concentration of 20 fmol/μL (40 μL)

  • x = length in bp ÷ measured ng/μL * 0.013 * 40
DNA length (bp) ng/μL Vol. (x) + dH2O
