RNA FISH-Cell Lines
Hybridization
Today I'm going to perform hybridization on the cell lines I fixed Saturday. I'll be using RBFOX3 (NeuN) and FOXP2 as my genes of choice.
Sample Matrix
Sample | Cell Line | uL RBFOX3-488 (ng) | uL FOXP2-594 (ng) |
A1 | BE2-C | 2 (110) | 2 (120) |
B1 | T98-G | 2 (110) | 2 (120) |
C1 | U-87MG | 2 (110) | 2 (120) |
D1 | NCI h1975 | 2 (110) | 2 (120) |
- Prehybridize slides ~ 1 hour+ at 70C with prehybridization solution
- Determine probe concentration (usually 2-4ng/ul) and denature probe at 90C for 10-15 minutes.
- Drop temp to 65C
- Spin briefly. Do not open the tube when it is at 90C-probe loss can occur.
- Add about 50-100 ng of probe to each slide in appropriate buffer; should be ~25 uL
- Seal coverslip with rubber cement, wait ~5 minutes for cement to dry
- Hybridize overnight appropriate temperature
- VARIABLE--shorter probes may want much lower temp; Hybridization temp may need to be determined empirically (=many trials…….)
- important to keep slides in a humid environment
- Prehybridization solution:
- 50% deionized formamide
- 50% 2xSSC pH 7.0
- Add dextran sulfate to 1%
- Hybridization solution (Arjun Raj)
- 2X SSC
- 10% Formamide
- 10% Dextran Sulfate
- 0.02% RNAse-free BSA
- 50 μg E.coli tRNA
