Entry title

Miniprepped colonies picked yesterday

Part number 260 280 260/280 ng/ul
F2620 miniprep 1 0.052 0.027 1.881 51.662
F2620 miniprep 2 0.024 0.014 1.679 23.941
J06702 miniprep 1 0.039 0.022 1.766 38.85
J06702 miniprep 2 0.057 0.032 1.782 56.501
F2620-E0240 miniprep 0.046 0.026 1.794 45.856


Want to build F2620-J06702. Will try having F2620 as a front insert and J06702 as the backbone as well as F2620 as the backbone and J06702 as the rear insert.

Digests:

Number Part number Enzymes Insert or Bb Expected band sizes Extracted band
1 J06702 X/P Rear insert 869 + 2070 869
2 J06702 X/E Backbone ~2900* ~2900
3 F2620 S/P Backbone ~3100* ~3100
4 F2620 E/S Front insert 1061 + 2070 1061
5 F2620-E0240 X/P N/A 1920 + 2070 N/A

'*Not totally sure what the backbone length is. Because of the low mini prep yields for 1-4, I used more DNA for digests 1-4:

Plasmid 25ul
MM 3ul
Enzyme 1 1ul
Enzyme 2 1ul
H20 0ul
Total 30ul

For digest 5, I made a lower reaction volume because it's only to confirm:

Plasmid 10ul
MM 2ul
Enzyme 1 1ul
Enzyme 2 1ul
H20 6ul
Total 20ul

Digests ran for 20 min at 37deg
Gel looked good but the J06702 vector is ~1kb longer than expected.

Part number 260 280 260/280 ng/ul
J06702 X/P 0.001 0.001 0.833 0.526
J06702 X/E 0.01 0.007 1.446 10.002
F2620 S/P 0.015 0.009 1.709 15.477
F2620 E/S 0.002 0.001 1.8 1.915


Ligations

Rxn 1 Rxn 2
Bb F2620 S/P 3.3ul J06702 X/E 5ul
Insert J06702 X/P 13ul F2620 E/S 13ul
2x Roche buffer (Behzad) 17.3ul 19ul
T4 ligase 1ul 1ul
H20 0ul 0ul
Total 34.6ul 38ul

Ligation reactions ran for 15min at room temp. Agitated occasionally.
