Isolation: Isolation date: July, 1979
Receptors: epidermal growth factor （EGF）
Cytogenetic Analysis: modal number = 62; range = 43 to 64.
The modal chromosome number was found in 78% of the cell population. The rate of polyploidy was 2.4%. Three consistent chromosome markers were identified: M1: del（1）9 ?; M2 del（13） and M3. Chromosome #20 is trisomic and the X chromosome is found in the disomic condition.
Age: 2 to 3 years
Gender: male
Comments: 12MBr6 is an epithelial cell line derived from secondary bronchial tissue of a 2- to 3-year-old normal African green monkey. This line was initiated in June, 1979 at the American Type Culture Collection from tissue explants using penicylinders and a trypsin-versene solution for cell dispersal. These cells contain PAS-positive cytoplasmic inclusions. Epidermal growth factor （EGF） was used to initiate and maintain growth. Post-freeze longevity studies indicate that EGF is an essential component of the culture medium for successful long-term propagation of the cells. Progeny from the 12MBr6 were found to undergo at least 23 additional doublings beyond the frozen state.
Propagation: ATCC complete growth medium: Ham's F-12K Medium with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and supplemented with 30ng/ml epidermal growth factor and 10% fetal bovine serum
Atmosphere: air, 95%; carbon dioxide （CO2）, 5%
Temperature: 37.0°C
Growth Conditions: The line requires epidermal growth factor as a supplement to the medium.
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.
