Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
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.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended
Medium Renewal: Every 2 to 3 days
