| Disease: | adenocarcinoma |
| Age: | 12 month old |
| Gender: | female |
| Strain: | LT/Sv |

| Derivation: | LTPA is an epithelial cell line derived in 1975 by Edward H. Leiter at The Jackson Laboratory, Bar Harbor, Maine from a spontaneous pancreatic adenocarcinoma taken from a 12 month old female Lt/Sv mouse. |
| Comments: | A defective Polyoma virus infection of a pancreatic duct cell or its precursor appears to represent the neoplastic transforming event. LTPA cells carry a persistent Polyoma infection. When injected subcutaneously into Swiss nu/nu mice, LTPA cells formed ductular structures, which were destroyed by inflammatory reactions within 3 weeks. A culture submitted to the ATCC in May of 1998 was found to be contaminated with mycoplasma and progeny were cured by a 21-day treatment with BM Cycline. The cells were assayed for mycoplasma, by the Hoechst stain, PCR and the standard culture test, after a six-week period following treatment. All tests were negative. |
| Complete Growth Medium: | The base medium for this cell line is ATCC-formulated Eagles Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
| 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.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994. |
| Cryopreservation: | Complete culture medium 95%; DMSO, 5%. Cell culture tested DMSO is available as ATCC Catalog No. 4-X. |
