USER/DpnII digested 0 gap probes:
Noi made 11.36ug/~400ul 2013-5-29 I made 10.58ug/180ul 2013-5-16
To run ~3ug/gel, I use ~100ul of probes that Noi made for each of the 4 gels
- Ran TBU gel at 220V for 30 min with samples and ladder prepared below
- Heated TBE buffer in microwave
- Denatured samples/ladder for 10 min at 75C before putting on cold rack for 1 min
- Size selected for brightest band below 200bp
Components | 1X Volume | 4X Volume |
Enzyme digested probes (~11.36/400ul) | 106 | 424 |
TBE-Urea Buffer 2X | 106 | 424 |
H2O | 0 | 0 |
Total | 212 | 848 |
Components | 1X Volume | 4X Volume |
10-bp DNA ladder (1 ug/ul) | 1 | 4 |
TBE-Urea Buffer 2X | 5 | 20 |
H2O | 4 | 16 |
total | 10 | 40 |
First Strand cDNA synthesis
- Followed NEB E6300S protocol: [1]
Got 2ul aliquot of Human Brain Reference RNA from Blue at concentration 1ug/ul
- Mixed components in two 0.2 ml microfuge tubes labelled HBBR 1ug cDNA
Components | Volume | 2X Volume |
RNA | 1 ul (1 ug) | 2 ul (2 ug) |
d(T)23VN (50uM) | 2 ul | 4 ul |
H2O | 5 ul | 10 ul |
Total | 8 ul | 16 ul |
- Denatured RNA for 5 min at 70C and then put on ice
- Tightened the thermocycler too much and bent the tube slightly out of shape
- Added the following to each tube
Components | Volume |
M-MuLV Reaction Mix | 10 ul |
M-MuLV Enzyme Mix | 2 ul |
Total | 20 ul |
- Incubated for one hour at 42C
- Inactivated enzyme for 5 min at 80C
- Kept on ice
Second Strand cDNA synthesis
- Follow NEB E6111S protocol: [2]
- Added 48 ul H20 to each tube
- Added 8ul 10x Second strand synthesis reaction buffer
- Added 4ul Second strand synthesis enzyme mix
- Mixed by pipetting
- Incubated for 2.5 hours at 16C
- Purified using Qiagen minelute column (eluted 23ul into 1.5ml tube labelled HBRR cDNA)
- Measured DNA conc with Nandrop:
- ___ul (__ug) sample left in each tube
