C Probe Hybridization Test
This will be the first test of the C Probe hybridization protocol for Combo-Lock. I have been growing U87MG cells for several days now and am ready to passage them. When I passage I'll take the remaining 90% for this test. Since I don't have the antibodies ready yet (I am waiting on some columns) I am just testing the C Probes.
Protocol
Buffer and Reagent Prep
- Ribonucleoside Vanadyl Complex-to minimize freeze thaws, thaw at 65C for 10 min; store in 1 mL aliquots
- Resuspend following primers to 100 uM (pmol/uL) <o1 type="i">
- C Probes (40 uL to 100 uM): CAV1-C1/C2,GFAP-C1/C2,SOD1-C1/C2,VIM-C1/C2
- Primers (uL to 100 uM): P2 (295), P4_RC (295), P6 (316), P12-RC (323)
- Wash Buffer
- Hybridization Buffer-Make 10 mL at a time and store in 1 mL aliquots
- Fix cells (CERC)
- Start with confluent U87MG cells
- Remove media (EMEM) and wash with 1X PBS
- Trypsinize cells using 0.5 mL trypsin LE express; incubate 5 min at 37C
- Resuspend cells in by adding 4.5 mL media; use 0.5 mL to passage
- Pellet remainder of the cells in a 15 mL Falcon tube at 600g for 3 min
- Remove supernatant
- Fix cells in 5 mL EMEM with 1.6% paraformaldehyde for 10 min at RT
- Pellet cells by centrifuging at 600xg for 3 min
- Wash cells with 5 mL wash buffer
- add 0.5 uL RNasin (40 u/uL) to 5 mL wash buffer prime
- Pellet cells and add 5 mL ice-cold methanol to permeabilize; incubate 10 min on ice
- Wash Buffer: 1X PBS, 0.1% Tween-20, 4 U/mL RNasin
- Hybridization Buffer: 1X SSC, 20mM RVC, 40 U/mL RNasin, 0.1% Tween 20, 100 ug/mL salmon sperm DNA
