Applications: transfection host

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 lack GlcNAc glycosyl transferase so that N-linked carbohydrates are blocked at the Man5-GlcNAC2-Asn intermediate. The line may be useful for studying the effects of altered N-linked glycosylation on the function and compartmentalization of endogenous glycoproteins or glycoproteins introduced by viral infection or transfection of foreign DNA.

BR>The population contains Pro+ revertants at low frequency (approximately 1 in 100,000 cells), and should be suitable for complementation studies which require the Pro- marker.

Lec1細胞The cells are proline auxotrophs and must be grown in a medium that contains proline (40 mg/L).

The population contains Pro+ revertants at low frequency (approximately 1 in 100000 cells), and should be suitable for complementation studies which require the Pro- marker.

Propagation: ATCC complete growth medium: Alpha minimum essential medium with ribonucleosides and deoxyribonucleosides, 90%; fetal bovine serum, 10%

Temperature: 37.0°C

Subculturing: Protocol: Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.

Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended

Medium Renewal: 2 to 3 times per week

Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5%

Storage temperature: liquid nitrogen vapor phase
