C Probe Hybridization[edit]

Back to Notebook

This page describes the protocol for hybridizing C probes as used in PLAYR Design (as from Nolan lab paper).

Protocol[edit]

Resuspend oligos in nuclease free water to concentration of 100 uM
  1. Fix cells
    1. Pellet cells at 600g for 3 min and resuspend at concentration of ~1,000,000/mL
    2. Fix cells in medium with 1.6% paraformaldehyde for 10 min at RT
    3. Wash cells with wash buffer
    4. Pellet cells and permeabilize with ice-cold methanol for 10 min on ice
    5. Once in methanol cells may be stored long term
  2. Hybridization
    1. Pellet cells via centrifugation at 600g for 3 min
    2. Heat C probes to 90C for 5 min; Chill probes on ice to quench
    3. Add probes to cells for final concentration of 100 nM
    4. Incubate probes at 40C for 1 hour with vigorous agitation
    5. Wash three times with wash buffer and pelleting at 600xg for 3 min
    6. Incubate cells for 20 min at 40C in stringent wash buffer
