Cytogenetic Analysis: modal number = 90; range = 81 to 96. This is a hypotetraploid human cell line with the modal chromosome number of 90, occurring in 50% of cells. The rate of cells with a higher ploidy was 3.6%. This cell line has a very complex karyotype. There were 18 or more marker chromosomes that were common to most cells. Markers der(1)t(1;2) (p36.1;q21), del(1) (q2101) and several others had two copies per cell and t(2p14q), t(3q7p) and others had a single copy per cell. The Y/autosome translocation marker was identified as der(20)t(Y;20) (q11.23;q13.3) and had two copies per cell. The inclusion of a short segment of the euchromatic Yq11.23 was confirmed by the Southern blot DNA analysis. There were two normal X chromosomes per cell; Normal Y, N1 and N11 were absent; N19 had five or more copies per cell.

Comments: This is one of a very extensive series of melanoma lines (see also ATCC HTB-70,ATCC HTB-71 and ATCC HTB-73) isolated by T. Takahashi and associates.
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:
  1. Remove and discard culture medium.
  2. 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.
  3. 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 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 37°C.

Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 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
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
