Gender: female
Comments: This line is a mutant clone derived from the parental CHO clone Pro-5 (a proline auxotroph, see ATCC CRL-1781) by selection for resistance to wheat germ agglutinin.
The cells exhibit a drastic reduction in the transport of UDP-galactose into the Golgi compartment, and may be useful for studying the role of galactose residues in the function and compartmentalization of glycosylated macromolecules.
The cells are proline auxotrophs and must be grown in a medium that contains proline (40 mg/L).
The population contains Pro+ revertants at high frequency (approximately 1 in 250 cells), and should be cloned if it is desired to use the Pro- marker in complementation studies.
These cells may also be grown as a suspension culture if agitated. Keep the cell concentration between 2 x 104 and 1 x 106 cells/ml.
Propagation: Lec8细胞ATCC complete growth medium: Alpha minimum essential medium, 90%; fetal bovine serum, 10%
Temperature: 37.0°C
Subculturing: Protocol: Remove medium, add fresh 0.25% trypsin, let sit for 2 to 3 minutes, remove trypsin and let the culture sit at room temperature for 5 to 10 minutes or until the cells detach. Add fresh medium, aspirate and dispense into new flasks.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended
Medium Renewal: 2 to 3 times per week
