Welcome to Anand Kesavaraju's 140L Lab Notebook

  • Eco/Bam digest PCR products protocol today:

"8uL PCR material 1uL NEB Buffer 2 0.5 uL EcoRI 0.5 uL BamHI

When you do this, you'll run those digests in the thermocycler, so use PCR tubes to set them up. Also, you should NOT add DNA loading buffer before sending your samples upstairs to be run on the gel. It is dangerous to let an active digestion reaction sit with the extra glycerol present in the loading buffer--it can cause degradation of your DNA. You add the loading buffer right before loading the DNA into the gel."

  • Received email from Professor Anderson:

"I noticed on Friday that many of you were using the "AW Wash Buffer" for your Zymo cleanups rather than the "A4 Wash Buffer". Unfortunately, they are both called "Wash Buffer" but they are not the same. AW is equivalent to the Qiagen PB Buffer--it has quanidinium chloride in it. What you wanted was A4, which is ethanol/water. So, your DNA is probably now in the landfill.

I redid all your PCRs and Zymo cleanups and threw out all the old tubes. So, you're back on schedule. I've also modified the protocols and have ordered Qiagen minipreps to eliminate the confusion around the two kits. If you are printing out the protocols, please reprint them before doing things. These are the protocols you will be using:

  • Analytical Gel for sbb1140 - see Figure 2 below. No band appeared in lane 5, indicating PCR was unsuccessful..

  • Repeat sbb1140 (BseRImet) PCR - did not work last time.
  • Run analytical gel for both (just P_malP for today - see Image below, lane 7)

PCR of sbb1140 and sbb1107

  • Only PCR today
  • Oligos sbb1140F/R are freeze dried, so rehydrate with appropriate volume of ddH2O and perform a 1:10 dilution to get 10 uM
  • sbb1107F/R are already at 10 uM
  • Expand buffer/polymerase for genomic (MG1655 DNA)
  • Phusion buffer/polymerase for plasmid DNA (pBjh1601CA-Bgl009)

Followed the following Protocol for Cloning by PCR.

I herd u liek notebooks, so I put a notebook in ur notebook so you can look at Anand's Personal Page
