Both male and female diploid cells as well as pseudodiploid cells are present. Approximately 58% of the cells have a chromosome number within + or - 1 of the diploid and one dicentric chromosome is present in some cells of the population., Both male and female diploid cells as well as pseudodiploid cells are present.

Age:

Gender:
male and female mixed
Comments:
The Mv 1 Lu (NBL-7) cell line was initiated by A.J. Kniazeff, W.A. Nelson-Rees and N.B. Darby, Jr., in May, 1964, from trypsinized lungs of several nearly full-term, unsexed fetuses of the Aleutian mink.The cells are useful for focus forming assays for murine and feline sarcoma viruses [PubMed: 4366800].
Propagation:
ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. 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 which 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 37C 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 37C.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:4 is recommended Medium Renewal: Every 2 to 3 days
Preservation:
Freeze medium: Complete growth medium 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor temperature
