Update for everyone
As explained in pre-lab lecture, we were remiss (mainly me, Agi!) in not providing you with the best sequence information for V corneae. Moreover, we told you to shoot for a Tm of 58 °C instead of a Tm of 63 °C (Ta of 58 °C).
Below, we have listed modified primer sequences (just under your originals) that match the Broad sequence. An ApE file of this sequence is linked here.in progress
As a default, we will order these primers on Tuesday and Wednesday for arrival on Thursday and Friday, and run two separate PCRs: one at Ta = 58 °C and one at Ta = 53 °C.
However, if you would like to revise your primers to a Tm of 63 °C, we will accept these new designs through Monday at 9 pm for T/R section and Tuesday at 9 pm for W/F section.
T/R section
Please sign up for one of the design challenges -- four teams per challenge -- right away.
When you have finished, post your primer sequences (from 5' to 3') so that they can be ordered.
I will name your primers by the approximate base-pair that they target in V corneae or E hellem, so please share this information as well.
