Miniprep:

Made according to the protocol of Aisgen Miniprep Kit Elution in 50 ul. The RD2 #5 plasmids prep as some that have already been prepared will be sent for sequencing this afternoon.


Mediums

New medium were made to grow the double-transformed DH5 a (LovTap BB and RO2) -> should be without thy.

M9 was redone, pH adjusted with amino acid and filtred. for 1L:

5g glucose
6g Na2PO4
3g KH2PO4
1g NH4Cl
0.5g NaCl
0.12g MgSO4
0.01g CaCl2


Trp Operon synthesis

Using the Klenow fragments protocol and primers:

Trp operon Rev
Trp operon Fwd

Note : BBx means LovTAP biobrick. We identified 7 clones that worked, so x is the number of the clone. RO2#x : we have 4 clones that worked for the read out 2 but the RO2#8 seems to have a weird behaviour even if we know it has the insert, so we didn't use it afterwards.

Double transformation

We made a double transformation of RO2#4/BB1, RO2#5/BB3, RO2#8/BB5 and RO2#10/BB6.

We had each time a total volume of 10ul of DNA, with the same amount of each DNA. The standard protocol was used and the cells were then spread over plates containing Kana + Amp as antibiotics.
