Applications: transfection host
Receptors: glucagon; somatostatin; glucocorticoid
Comments: This line was established from a primary culture of Syrian hamster islet cells which were transformed with SV40.
The cells secrete up to 24 ng of insulin per 10 exp6 cells per 24 hours (passage 60).
HIT-T15细胞Insulin secretion is stimulated by glucose and glucagon, and is suppressed by somatostatin and glucocorticoids.
Insulin synthesis decreases with length of time in culture.
Propagation: ATCC complete growth medium: Ham's F12K medium with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate, 87.5%; dialyzed horse serum, 10%; fetal bovine serum, 2.5%
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Subculturing: Protocol:
Remove and discard culture medium.
Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that 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.
Interval: HIT-T15细胞An inoculum of approximately 1.3 X 10(5) viable cells per sq. cm is recommended.
Medium Renewal: 2 to 3 times per week
Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2004
recommended serum:ATCC 30-2020
