Tom and Arjan started with gas chromatography mass spectrometry. Test sample: 5gr. fresh meat incubated @ 37C for 3 houres. For both column (HP5 and CP wax) three runs on each column with different incubation and syringe temperature (1: 80C, 100C 2: 100C, 120C 3: 120C, 140C)


Nisa

Plasmid isolation pSB1C3-alsT promoter + GFP

NanoDrop result (ng/ul):
A1= 102.9
A2= 96,6
B1= 118,1
B2= 113,7
C1= 122,8
C2= 88 Comment: gel picture OK!
D1= 124,9
D2= 93,3

Result:
expected size: 3300bp for the pSB1C3 (2079bp)+ alsT (~500bp)+ GFP (800bp)

From the gel picture, only plasmid from colony C2 (promoter alsT300) showed the expected size. The other plasmids seem to be empty, probably due to self ligation.

Solution: Check plasmid from other white colony

re do transformation. Increase the ratio of plasmid backbone: insert gene


Building backbone biobrick for B.subtilis

plasmid pSac-Cm: integration plasmid, double cross over in SacA region

add double terminator, BBa_B0015, and prefix-suffix: XbaI, SpeI, PstI


How to?

Cut backbone with HindIII and EcoRI

Cut BBa_B0015 with HindIII and EcoRI

Now we have separate parts ready to use for ligation into our biobrick device
