Test 50 cell level
- Test different isolation condition for 50 cells (sperm, ES)
- NC: NTC; 150pg gDNA (~25 cells)
- PC: 10pg, 100pg, 500pg RNA
Samples
- Zymo microprep kit for total RNA isolation on 1 tube of sperm and 1 tube of ES (elute with 7ul, 3.3ul each mixed with lysis buffer (-NP40)
- 10ul lysis buffer (+ 0.45% NP40)is directly added into 1 tube of sperm and 1 tube of ES (carryover PBS is huge for sperm), mix and RT for 5min, then 4.55/5 ul each is continued with R.T.
- 5 controls (0.5ul in 4.05ul lysis buffer with NP40)
Procedure
- Isolation of total RNA, elute with 7ul
- 10ul lysis buffer at R.T. for 5 min
- Lysis: 70C, 90sec
- RT: 42C, 15min; 70C, 15min
- ExoI-SAP: 37C, 30min, 85C, 15min
- A-tail: 37C, 15min, 70C, 10min (TdT was not enough,so I added 3.2 instead of 4.2ul. But considering the glycerol left in the enzyme tube, I am really uncertain how much I added.)
- 5 cycles of PCR: 95C, 3min; 50C, 2min; 72C, 3min (X 2) | 95C, 30sec; 50C, 1min; 72C, 2min (X 3)
- 25-30 cycles of PCR: 95C, 3min| 95C, 30sec; 67C, 1min; 72C, 2min+6sec/cycle (X 25-30)| 15C hold
