The cells are negative for glial fibrillary acidic proteins and S100 (S-100) protein.

Stimulation of the cells with Fas ligand lead to apoptotic cell death within 16 hours. The cells were also killed by puromycin in a dose dependent manner.

Bcl-2 protects these cells from Fas ligand-induced cell death but was shown to have only a small protective effect on puromycin-induced apoptosis.

Information received from the depositor indicates the maximum number of serial subcultivations since origin is approximately passage 550. Current lots are available at approximately passage 539.

1. Remove and discard culture medium.
2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53% (w/v) EDTA solution to remove all traces of serum that contains trypsin inhibitor.
3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
   Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
5. Add appropriate aliquots of the cell suspension to new culture vessels.
6. Incubate cultures at 37°C
