Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Gender
female
Applications
This cell line exhibits a drastic reduction in the transport of CMP-sialic acid into the Golgi compartment, and may be useful for studying the role of sialic acid in the function and compartmentalization of glycosylated macromolecules.
Storage Conditions
liquid nitrogen vapor phase
Derivation
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.
Clinical Data
female
Comments
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 25 cells), and should be cloned if it is desired to use the Pro- marker in complementation studies.
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
Name of Depositor
P Stanley
Deposited As
Cricetulus griseus
