    • component B
  • equipment 1
  • equipment 2

Procedure

Day 0

  1. Trypsinize 3T12's (1 confluent T175 will yield approx. 10-40x106,\sup> cells) and resuspend at 2.5-2.5x106<\sup>/ml in DMEM-10.
  2. Aliquot 2/ml/well (3-5x105</sub> cells/well) into 6-well plates. Don't swirl the cells, as you may end up with all your 3T12's in the center of the well.
    1. Need one 6-well plate per viral sample. (This will let you test 6 logs of dilution)
  3. PrepareMethylcellulose, if necessary.
  4. Freeze/thaw/freeze your viral sample, if necessary.
