Beta-TC-6 小鼠胰岛素瘤胰岛β细胞
Comments: The cell line was derived from a pancreatic tumor （insulinoma） arising in a transgenic mouse. 
The mouse carried the pseudogene construct composed of the SV40 early region controlled by the rat insulin II gene promotor. 
The cells contain abundant insulin and small amounts of glucagon and somatostatin. They secrete insulin in response to glucose. [46884] 
Propagation:  ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: heat-inactivated fetal bovine serum to a final concentration of 15%. 
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.
