Bglii Digest (Sense)

From the results last week, I realized that the original primer for Bglii cutting (the DNA must be double stranded and the RCA product is single stranded) was in the wrong sense. This is because the RCA product will be the reverse complement of the circular product. So I'm repeating the Bglii digest from last Thursday using the correct primer.

Also, because I'm having trouble keeping track of everything, here are all the letter codes used for the experiment. For future readers, just pay attention to the conditions and maybe sample numbers (Sample 1: Sample, 2: No Template, 3: No C Probe, 4: No PO4 on padlock).

Sample Matrix

Letter Code Condition Samples
X PostRCA-Unpurified 1-4
Y PostRCA-Purified 1-4
Z Unpurified post Bglii Digest (X) 1, 4
Q Purified post Bglii Digest (Y) 1, 4
S MaxRCA-Unpurified 1-4
T MaxRCA-Purified 1-4
V Unpurified post Bglii Digest (S) 1, 4
W Purified post Bglii Digest (T) 1, 4
J Unpurified Bglii Digest-Sense (X) 1-4
K Purified Bglii Digest-Sense (Y) 1-4
