For protocol see here: Resuspension of T, B, and HP oligos

Resuspension

pmols:17718

1. add 177uL of .1x TE
2. After addition of liquid I vortex the solution for about 1 min.
3. Let the stocks sit on ice for 60'
4. Vortex for 1min again.
5. Take nanodrop reading:
   • 820ng/uL - with a MW of 8929g/mol this gives me a concentration of 92uM which is close enough! ^{SJK 01:06, 3 September 2009 (EDT)}

     Yup, that's definitely about as close as I usually got!

   • again, we want 100uM

Annealing

The idea is to heat and quick chill. So I am going to follow the protocol on above mentioned page: 5min at 100C and 5min on ice.

I really don't want to make a google doc for this one reaction so I'll just detail below:

1. made annealing buffer from 10x TE and 3.8M NaCl:
   • 1uL of 3.8M NaCl in 75uL 10x TE (that is my logic to get 50mM NaCl + TE)
2. combined
   • 6uL sapcap
   • 10uL 10x anneal buff
   • 84uL ddH2O
3. heat at 95C for 5 min
4. cool on ice for 5 min
5. store in box #3 as Sap Cap

Tomorrow is ligation day.

Basing off the above results, I put 5ug DNA in the above reaction. That will give me 50ng/uL in solution for a total of 5.6uM. I don't know if making it double stranded will decrease the molarity or what. I could do a nanodrop, but I don't wanna.
