SmartPlus on Mouse Spinal Nuclei (Chun Lab)[edit]
Obtained sorted nuclei from Aran:
- 100 nuclei sorted directly into 2ul clontech dilution buffer (4x)
- 500 nuclei sorted directly into 2ul clontech dilution buffer (4x)
- 5000 nuclei sorted into BSA buffer (2x)
- stored 100/500 sorts at -80C. Removed 2 of each, vacuum spun down to 1ul for each.
- RNA extraction of 5000 using Zymo Micro RNA Kit (including DNAse treatment). Eluted in 6ul and vacuum spun down to 2ul.
- Performed SmartPlus protocol as per C1 tube control protocol on 1ul of above samples (only modification is addition of randomer) using 21 cycles for PCR
- cDNA Yields:
Sample | Sample Concentration (ng/ul) |
NC | 0.999 |
RNA 1 | 72.1 |
RNA 2 | 40.0 |
100 nuc 1 | 7.93 |
100 nuc 2 | 8.75 |
500 nuc 1 | 5.20 |
500 nuc 2 | 6.25 |
- Yields for the RNA 1 and 2 samples are too high (expect more of that seen for the 100-500 nuclei), therefore repeated PCR on RT reaction using 3 less cycles (18 total)
Sample | Sample Concentration (ng/ul) |
NC | 0.396 |
RNA 1 | 11.5 |
RNA 2 | 4.34 |
