pALS PCR 7 (titration) results – SUCCESSFUL


Hooray! While the gel image isn’t the best picture ever (thanks phone), the good news is that the PCR reaction worked for every MgCl2 concentration and seems to work best at 3.5-4.5mM. Also it should be noted that lane 3 contains a visible band, but there was some smudge on the filter so it blocked the light from that lane. Here are the lane assignments:

  1. 1kb ladder
  2. 1mM MgCl2
  3. 1.5mM
  4. 2mM
  5. 2.5mM
  6. 3mM
  7. 3.5mM
  8. 4mM
  9. 4.5mM
  10. 5mM

I have purified the reactions and according to the nanodrop, I have about 11ug of DNA which translates to 87nM (233ng/ul) of tetherable DNA.

I found some EpBR (EarI digested pBR322 and gel extracted) so I’m going to digest some of this new pALS DNA with BstXI, purify, and then ligate with both adapters. If all goes according to plan, I’ll have all the unzippable DNA I’ll ever need!
