| Applications |
The IA-XsSBR epithelial-like cell line is a radiation (X-ray) induced small intestine adenocarcinoma derived from an adult male Holtzman rat. The cells are sensitive to lysis by peripheral blood lymphoid cells from Fischer F344 rats having colon and pancreatic tumors induced by 1,2-dimethylhydrazine or 7,12-dimethylbenz(a)anthracene. |

| Subculturing |
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
- Remove and discard culture medium.
- 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.
- 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.
- Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
- Add appropriate aliquots of the cell suspension to new culture vessels.
- Incubate cultures at 37°C.
Subcultivation Ratio: 1:4 to 1:8
Medium Renewal: Every 2 to 3 days
