b promoter and a temperature-sensitive simian virus 40 large T antigen. At a non-permissive temperature (37°C-39°C), the cells cease to proliferate and begin to detach from the plate. Cells in culture display some microvilli formation and expression levels of the brush border-associated enzymes, alkaline phosphatase, dipeptidyl peptidase IV, and sucrase, can be induced in the line by the addition of 1mM sodium butyrate, 1 µM Phorbol Myristate Acetate (PMA), or 1 µM Retanoic Acid (RA) to the culture medium for 5 days. Conversely, the addition of 5 µg/ml TGF-β or 1 µM Bt2GMP will downregulate the two enzymes.

Propagation:

The base medium for this cell line is Prigrow II medium available at abm . To make the completed growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%, Penicillin/Streptomycin Solution to a final concentration of 1%, and Recombinant Murine IFNG to a final concentration of 5 ng/mL.
The expression of alkaline phosphatase and dipeptidyl peptidase IV can be upregulated by the addition of 1mM sodium butyrate, 1 µM Phorbol Myristate Acetate (PMA), or 1 µM Retinoic Acid (RA) to the culture medium for 5 days. Conversely, the addition of 5 µg/ml TGF-β or 1 µM Bt₂GMP will downregulate the two enzymes.
Carbon dioxide (CO₂): 5%, Temperature: 33.0°C.

abm does not recommend to use heat-inactivated FBS for cell culture unless specified otherwise.

Quality Control:

1) Immunohistochemical staining was used to detect the presence of SV40 large T antigen and keratin 18; 2) Biochemical assays (i.e. method of Nagatsu et al and method of Dahlquist) were used to measure brush border-associated enzymes alkaline phosphatase, dipeptidyl peptidase IV and sucrase.
