The Ac 711 cell line was derived from the mammary tumor of a transgenic mouse carrying the  Zeta-Globin-v-Ha-ras transgene.

The  Ac 711 cell line was derived from the mammary tumor of a transgenic mouse carrying the  Zeta-Globin-v-Ha-ras transgene. 

Ras proteins are essential components of signaling networks controlling cellular proliferation, differentiation and survival. 

Over expression of Ha-Ras has been shown to be correlated with tumor progression, and cell transformation.  

The cell line Ac 711 overexpresses Ha-Ras. It is useful in the studies of the activation and requirement for Ras signal transduction pathways in mammary gland tumors.

1. Remove and discard culture medium.
2. Briefly rinse the cell layer with Ca++/Mg++ free Dulbecco's phosphate-buffered saline (D-PBS) or 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
3. Add 1.0 to 2.0 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. An inoculum of 8 X 10⁴ to 1.5 X 10⁵ viable cells/cm² is recommended.
6. Incubate cultures at 37°C. Subculture when the cell concentration is between 3 X 10⁵ to 4 X 10⁵ cells/cm².
