Stage 2 Test

Back to Calendar

The purpose of this experiment is to test the latch and padlock binding, termed stage 2 (at the moment). This is based on the success of the VIM binding for both C-Probes and antibodies.

Experiment

Sample Matrix

Sample VIM-C1 (1 uL) VIM-C2 (1 uL)
Sample 1 X X
Sample 2    
  1. C-Probe Hybridization
    1. Split cells into 2 samples (1 mL methanol each)
    2. Pellet cells via centrifugation at 600g for 3 min
    3. Put 1 uL C1 Probe and 1 uL C2 probe into a 0.2 mL tube
    4. Heat C probes to 90C for 5 min; Chill probes on ice to quench
    5. Add probes to CPH buffer for final concentration of 100 nM (Add 1 uL probe mixture to 0.5mL hybridization buffer)
    6. Incubate probes at 40C for 1 hour with vigorous agitation
    7. Wash three times with 200 uL wash buffer and pelleting at 600xg for 3 min
    8. Incubate cells for 20 min at 40C in 200 uL stringent wash buffer
  2. Latch and Padlock Hybridization
    1. Pellet at 600xg for 3 min and remove supernatant
    2. Resuspend pellet in 50 uL LPH buffer with 100 nM insert/backbone oligos for 30 min at 37C following the sample matrix
    3. Sample Matrix
