Competence of Bsu9716:

Bacteria from 2/8/16 in fridge (Dj)
50 ml LB and 10 uL Kan added (so total 150 mL and 15 uL Kan) and cells back in incubator
Spin (4000 rpm 10 min) 50 ml X 2 and used pellet for competency
Spinned again same way after pulling both pellet together
Changed medium (50 mL LB + 5 uL Kan) and put it back at 4 degrees

2 mL of SpC BSU in SpII and 90 min incubation 37 degrees with shaking

Note:
Originally 1.2% of the dihydrate form so made the calculations in function of that; and Sofiane had to make a second batch
50% (w/v) glucose was filtered
No tryptophan added for the cell growth
Plates from 03/08/2016 (Zinebe)
Contains lawn and colonies ⇒ Not sure which are the B. subtilis.
Diluted some of the lawn and the colony each in 200 uL LB and plated it on LB-Kan then 37 degrees overnight

Note:
LB used for dilution was contaminated
When picking the colony with a tip some of the lawn was scraped with it
Pick primers and autoclaved MilliQ at school
Plates (from 04/08/16) (DJ)
Both plates had lawns on them however the plate containing the colony (along with some lawn and labelled Isolate) was green which was weird
Took plate from 3/8/16 and streaked on a plate divided in 3 a single colony, the lawn, and for the last portion, 10 uL of the B subtilis solution in the fridge was diluted in 200 uL of LB before streaking it.
The rest of B subtilis solution in the fridge was spinned, diluted in 10ml LB and divided in 2 x 50 mL tubes, 5 uL of Kan was added in each. Both were put back in the fridge
Tris HCl made by Kevin
All streaks grew well so we put them in fridge

Nothing done at the bench this week because of material issues

Tris-EDTA preparation (Sofiane):

1. ➟ 10mL 1M Tris pH 7.5 + 2mL 0,5M EDTA pH 8.0


2. ➟ 0,5M EDTA : 18,6g EDTA + 100 mL H2O. Ajuste pH 8.0 with solid NaOH (2,6g)


3. ➟ 1M Tris : 30,285g + 205 mL H2O. Ajust pH 7.5 with HCl.

Note : pH ajustment failed, I add 25mL of 12% HCl and 12 mL of 20% HCl to have a pH 7,6.
Concentration is not good anymore. We have to make this solution again. Maybe buy TE Buffer? Verification of TE we have is needed!
Competency test (Djamila/Zinebe)
Chloramphenicol (cm 25 mg/mL) preparation:
0.25 g diluted in 10 mL EtOH 95%; aliquots at -20
Note: first dilution in milliQ water by mistake
Got rid of water and tried to let it dry but without success so will probably just add directly EtOH in to make more Cm

Cm (Cf = 5 ug/mL) LB plates:
70 mL melted LB agar + 14 uL c
Note: agar cooled too much before pouring plate (only got 3 plates) so made more 100 mL melted LB agar + 20 uL cm

Competency test (CT)
Made SpII-EGTA solution (solutions made yesterday by Sofiane
T base 200 ml :

1. ➟ 50% (w/v) glucose 2 ml
2. ➟ 1.2% (w/v) MgSO4·3H2O 14 ml
3. ➟ 10% (w/v) Bacto yeast extract 2 ml
4. ➟ 1% (w/v) casamino acids 2 ml
5. ➟ 4 ml EGTA (0.1 M, pH 8.0)

Aliquots put at -20°C
After thawing competent BSU9716 at 37C in incubator (water bath had issues), added 500 uL of SpII-EGTA and mixed up and down.
Added 50 uL bacteria in 5 eppendorf tubes after spinning CT plasmids, added 1 uL of DNA in the appropriate tube (50pg/ul, 20pg/ul, 10pg/ul, 5pg/ul, 0.5pg/ul).
Bacteria+DNA mixture incubated at 37°C with shaking (150 rpm) for an hour
Spreaded the bacteria on Cm LB agar plate then put at 37°C overnight
At this point from the rest of competent bacteria, 100 uL spread on Kan plates
Note:
Should have spread the transformed bacteria on Cm and Kan plates
Competency test kit contains five vials of purified DNA from BBa_J04450 (RFP construct) in plasmid backbone pSB1C3 (cm resistant). Each vial contains DNA at a different concentration: 50pg/ul, 20pg/ul, 10pg/ul, 5pg/ul, 0.5pg/ul.

Plasmidic DNA Extraction on the liquid cultures made Sunday by Nassim and Wilhelm (Zinebe)
--> Followed protocol: “Monarch plasmid miniprep kit” from NEB

Note: First centrifugation of 10 mL, but only 5ml needed, so we re-suspended them in 5mL and centrifuge again.
DNA concentration obtained using Nanodrop

Plasmid Name	Plasmid Concentration (µg/mL)	260/280	260/230

Competency test check (Djamila) done on Friday 19th failed (Boys checked on Saturday) ie bacteria but no rfp from igem plasmid next step?

BSU9716 Plates from Sunday 20th(Wilhelm/Nassim)
No growth on Kan/Cm and Amp, plate back on Kan, Cm and Amp individually (from “loan plate”) and also frozen from initial BSU batch on LB then 37 degrees overnight

Oligo dilution in TE 1X (Sofiane) final concentration 100 uM, at -20

BSU9716 Plates from Monday 20th(Djamila)
Cells on Kan but not on Amp and Cm; should had have it on Kan and Cm so don’t use anymore “loan plate” as BSU9716 source.
Frozen on LB grew, so put it (chose 4 isolates and 2 locations on loan) on Kan/Cm and 37C overnight (Sofiane)

Made more LB agar 15g agar 1L LB

Liquid solutions (not from isolates but loan for bsu and directly from tube in which came from) of pEN and BSU9716 in 10 mL of LB gent (10 ug/mL) and Kan/Cm (50//25ug/mL), respectively, for tomorrow and plated both on appropriate antibiotic

Preparing lysozyme aliquot (Zinebe) :

Concentration = 20g/L :
→ 0,0220 g lysozyme in 1,1 mL miliQ water (mix with vortex)

1.2% Gel of Gent amplification PCR product (Djamila)
1.2 g Agarose 100 mL TAE 1X 10 uL (10000 X) Gel red

Samples:
5 uL DNA, 4 uL loading dye, 11 uL MilliQ H2O Run 90V 45 min then 120V 55 min

Gent resistance gene size: 534 bp Band looks like it’s around the expected size

Note: Have same amount of DNA in all well and this was supposed to be a gradient PCR.
Therefore, it looks like all temperature are working well. Next PCR simple instead of gradient then if don’t work will do gradient
Run PCR for fragment A and B

Note: issue with PCR of B; when looked at the TC to check evolution there was an error and we assumed the beginning of the PCR was done so we just did the final elongation step.
Run gel for fragment A and B (second half of the 1.2% Gel of the morning)
3 uL of DNA + 4 uL of loading dye + 13 uL milliQ H2O
Run 140V 30 min 160V 30 min
Band around 500 bp for A and nothing for B. Not surprising since maybe no PCR was done on it. Start over the B tomorrow and join A and Gent. Maybe purify do bigger volume and purify PCR before joining them.
