MV1p12 ECIS experiment using serum free media

May 10th, 2009

After 72 hours, MVR1p12 cells were ready for experiments using ECIS arrays.
400uL of serum free media with DMEM and 1% PCN/ST was exchanged with existing media and incubated for 2.5 hours.
ECIS arrays were connected and data recorded for 2 hours to establish baseline.
100uL of serum free media was removed from each ECIS well and replaced with 200uL of media+CSE+T10 to achieve concentrations according to previous experiments.

Wound Assay using MV1p12, 10% CSE and serum free media

May 10th, 2009

MV1p12 cells were ready for wound assay with 100% confluence 72 hours after plating into 35mm plate.
2mL Serum free media using DMEM + 1% PCN/ST was exchanged into 35mm plate.
200uL of CSE was added to achieve 10% CSE concentration.
Wound simulated using 200uL pipette tip and placed under video scope for 24 hours.

Method for cigarette smoke extract production

April 1st, 2009
  1. 500ml vacuum bottle filled with 200ml of PBS was connected to suction apparatus with suction catheter below level of PBS.
  2. Using a suction catheter connected to a 1000ml pipette, 20 unfiltered research cigarettes (1 pack) were lit and “smoked” using the vacuum port at a burn rate of ~2minutes/cigarette.
  3. The optical density of the resulting PBS mixture was 2.175 at 260nm wavelength
