When you do a digest, make sure you label the tubes clearly and be sure to include the name of the enzymes you used to do the digest.

- Developed the Westerns after an overnight exposure. Blank yet again. James thought the problem was due to the development solution used - it was an old tube in the fridge that had been mixed months ago and was probably no good anymore. New solution was made and applied, film was exposed for 60 seconds and again, there were no results. This is odd because there were obvious thick bands of overexpressed proteins when we did the Coomassie staining. We will need to set up some cultures when we use the Ni-NTA columns so perhaps we will do them in duplicate and use one set for Westerns again.

Lab Tip of the Day
When you do a digest, make sure you label the tubes clearly and be sure to include the name of the enzymes you used to do the digest. Since the BioBricks make use of multiple enzymes, it is important to know what has been digested with which, so the parts will fit together properly upon ligation.
