Jacob and I are working on getting amino acid genes into biobricks. We're on our fourth (?) ligation with some of them because they haven't been working... We suspect the ligation step has been causing the trouble and we altered the protocol slightly - 3:1 insert to vector ratio (in uL) as opposed to the 2:2 used previously, and using NEB Buffer 3 as opposed to Buffer 2 (to optimize EcoR1 and PST1 activity). We also left the ligation mix sitting at room temperature beginning at 5 pm overnight. Jacob will transform the cloned vectors into competent cells (K12?) and plate them tomorrow morning (~9 am). This increases the ligation process from 1.5 hours (June 20) to 16 hours.

The genes I digested and ligated:

  • Trp A
  • Trp B
  • Tyr A
  • Met A
  • Arg C

Jacob and I digested/ligated/transformed those listed above yesterday as well, but Arg C has replaced Arg E today because the Arg E cells grew several (~5) colonies! Success!

I also (re)ligated the pSB1C3 vector left over from last year (about 8 months old). It has the RFP gene cloned into it. This was to (1) amplify the number of cloned vectors, and (2) to check if our ligation protocol is effective.

Joe was digesting 2 of the dsz genes and planned to ligate tomorrow.
