Properties
        | Karyotype | modal number = 49; range = 42 to 55. The cell line is aneuploid human male, with chromosome counts in the near-diploid range. However, the near-tetraploid population may become predominant within very few passages. The 48 and 49 chromosome karyotypes had a single X and a single Y chromosome. Three of the karyotypes at higher ploidy had two X chromosomes and a single Y chromosome. Four marker chromosomes were identified: del(6)(q21), del(10)(p11), 14p+, 12p+. Marker chromosome M4 was not seen in the karyotypes prepared from higher ploidy metaphases. |

Background
        | Complete Growth Medium | 
				The base medium for this cell line is ATCC-formulated McCoy''s 5a Medium Modified, Catalog No. 30-2007. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.  | 
		
|---|---|
| Subculturing | 
				 
					Remove medium, and rinse with 0.25% trypsin, 0.53 mM 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 37¡ãC) 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
