09/08


Cell wall isolation according to protocol: Cell disruption, samples are frozen.


Culture Bascillus over night, all four strains: Rok, DegU, SigF, Sp0A


10/08


Cell wall isolation according to protocol: Cell disruption again, continue according to protocol


Dry-freeze over night


Culture Bascillus over a extra night, all four strains: Rok, DegU, SigF, Sp0A


11/08


Chaplin isolation:


4x approximately 15 mg dry cell wall (180 ul TFA),
4x approximately 10 mg dry cell wall (100 ul TFA),
8x approximately 5 mg dry cell wall (100 ul TFA),


Cultured bascillus strains are taken out of the stove, medium will be used for degredation experiment.


Pellicle: ROK + SigF



DEGREDATION EXPERIMENT:
3x appr. 5 mg samples + ROK, DegU, SigF medium (+ 1 control normal medium)
3x appr. 5 mg samples + ROK, DegU, SigF lysed medium (+ 1 control lysis normal medium)
3x appr. 15 mg samples + ROK, DegU, SigF medium (+ 1 control normal medium)
3x appr. 10 mg samples + ROK, DegU, SigF medium (+ 1control normal medium)

normal medium is with 2% glucose for lysis


normal medium is TY for the rest


12.45: lysis at 37 degrees for 1 hour, 20 mg/ml lysozyme (control also)


13.45: incubation with bacillus and control media

Hydrophobin samples were prepared for sds-gel at 14.00


Lysis samples were spinned off (13000 rpm/4 min), the samples were not boiled, the samples were prepared in 05,x SDS loading buffer


25 uL of sample was loaded on the SDS gel in the following order:


on gel 1:


5ulmarker-15ctrl-15sigf-15degu-15rok-rokl-sigfl-degu-l-ctrll-10ulmarker


on gel 2:


5ulmarker-10ctrl-10sigf-10degu-10rok-5ctrl-5sigf-5degu-5rok-10ulmarker


The 1 mm thick gel 1 was prepared using a 0,75 mm comb: Might be bad


Gel was runned on 60 v for 15 min


Then gel was runned on 120 v
