Gender female
Storage Conditions liquid nitrogen vapor phase
Karyotype modal number = 82; range = 74 to 84.
This is a hypotetra-/hypertriploid human cell line. The modal chromosome number is 82 occurring at 16% with polyploidy at 10.3%. The markers del(1)(q23), t(1q10p), del(7)(p13), t(7p18q), i(21q) and 5 others are common to all cells. They are all paired in most cells. N1 and N18 are absent, N11 is single-copied, and N6, N7, N8 and N16 are generally 4-copied (many cells also had 5 copies each for N7 and N8). The X is paired.
Derivation
This is one of a very extensive series of melanoma lines (see also ATCC HTB-70, ATCC HTB-71 and ATCC HTB-72) isolated by T. Takahashi and associates.
Clinical Data
female
Antigen Expression
Antigen expression: HLA A3,A29, Bw35,B40, Cw3,Cw4, DRw4
Tumorigenic Yes
Effects
Yes, in nude mice; produces malignant melanoma
Complete Growth Medium Minimum essential medium (Eagle) with 2 mM L-glutamine and Earle's BSS adjusted to contain 1.5 g/L sodium bicarbonate, 0.1 mM non-essential amino acids, and 1.0 mM sodium pyruvate, 85%; fetal bovine serum, 15%
Subculturing
  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 which 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 1:4 to 1:6 is recommended
Medium Renewal: 2 to 3 times per week
Cryopreservation
Freeze medium: Complete growth medium, 95%; DMSO, 5%
