Still no trace of plasmid present. Going to assume cloning did not work. Will try again next week with fresh phosphatase & ligase, using dephosphorylated backbone as another control.

Plasmid Miniprep of DBN001_pSB1A3 (repeat)

--Notes--

Once again, liquid culture density is very low. Suspect it's because there's no actual plasmid present.

--DNA Concentration--

Sample ID Conc. (ng/uL) St Dev (ng/uL) 260/280
DBN001_pSB1A3 colony 1 78.27 4.98 1.89
DBN001_pSB1A3 colony 2 59.95 4.37 2.14

--Restriction Digest--

Reagent Volume
DNA 600ng (7.7 - 10 µL)
10x FastDigest Buffer 3
EcoRI 1
PstI 1
Water 17.3 - 15
Total 30

Digest for 10 minutes at 37°C.


--Gel Electrophoresis--

Lost most of sample 1 while pipetting into the lane. Bands will probably be very faint.

Expected size fragments from EcoRI/SpeI digestion: 2132, 224

Still no trace of plasmid present. Going to assume cloning did not work. Will try again next week with fresh phosphatase & ligase, using dephosphorylated backbone as another control.
