week 5: 28 may - 3 june

Office work

This week a lot of new information was added to the wiki. There is now a team description, the journal has been for the most part updated and most of the protocols have been added. We've also worked further with the quaternary structure program, with minor succeses. Furthermore the logo is finished and will be uploaded on the wiki next week. Thursday evening we started thinking how to call our project, but the group is still divided. On friday we worked with the data of the Electron Microscopy and Dynamic Light Scattering and send the results and conclusions to our advisors. Hopefully the results will be posted next week on the wiki.

Lab work

CCMV test protocol:

Monday:

• Western Blotting
• prepared 10x Towbins electrotransfer buffer
• sandwich build-up:
  • case (white side)
  • sponge
  • Whatman paper
  • Whatman paper
  • nitrocellulose membrane
  • SDS gel
  • Whatman paper
  • Whatman paper
  • sponge
  • case (black side)
• all layers carefully soaked in 1x electrotransfer buffer
• run at 0.15A overnight in 4°C cold room
• missed a secondary antibody, no result available

Tuesday:

• Prepare samples for ultracentrifuge according to the protocol
• Starting ultra centrifuge, 45000 RPM for 3 hours

This was a very productive week, with good results. After the dialysis of last week, We began to prepare the CCMV samples for ultracentrifuge. After the preparation, the ultracentrifuge was started and the three hour wait began. Afterwards me made an appointment for thursday for the Electron Microscopy and the Dynamic Light Scattering machine.

Wednesday:

Thursday:

• Prepare the samples for EM and DLS
• Took pictures with EM
• Analized the particles with DLS

Thursday in the morning we prepared the samples for the Electron Microscopy and the Dynamic Light Scattering. Around 10:00 am we traveled to virology for the Electron Microscopy. After taking pictures, we traveled back to get our explanation for the Dynamic Light Scattering machine. We tested three samples; one wildtype CCMV, one CCMV-VLP and our own sample.

Friday:

CCMV & delta26 CCMV bricking:

Thursday:

• Prepare the
• Run PCR

Besides preparing and testing our samples, we've started thursday afternoon with PCR to brick our very first parts.

Friday:

• Started with digestion and ligation into the linerized backbone
• Transform the E.coli with our first bricks
• Grow over the weekend

The next day we worked further with the bricking. The PCR products were digested and ligated into our linerized backbones, to form our very first brick. The next thing to do was to transform our E.colistrain with our bricks. We must now wait till Monday to see if our transformation is succesful.
