Cell Line: KATO-III

Cell Description: Human gastric carcinoma; stomach; pleural effusion; from metastatic site: supraclavicular and acillary lymph nodes and Douglas cul-de-sac

Culture medium: Iscove´s modified Dulbecco´s medium with sodium bicarbonate, 2 mM L-glutamine and 1,0 mM sodium pyruvate + 20% FBS or RPMI1640 medium + 20% FBS

Subculture routine: Cultures can be maintained by addition or replacement of fresh medium, Adherent cells can be dislodged by scraping. Subculrture every 6 to 8 days.

Morphology: Spherical

Growth Properties: Suspension/monolayer

Karyotype: The stemline chromosome number is hypotetraploid with the 2S component occurring at 6,2%. Nine markers were common to most S metaphses, four markers were less frequent. One (occasionally 2 copies) homogenous staining region (HSR) t(11;HSR) was present in all metaphases examined, but no double minutes (DM) were detected.

Isoenzymes: PGM3, 1; PGM1, 1; ES-D, 1; GLO-1, 2; G6PD, B; Phenotype Frequency Product: 0.0742

AntigenExp: Blood Type B; Rh+

Tumorigenic: Yes; in cheek pouches of anty thymocyte serum treated hamsters; not tumorigenic in nude mice.

Depositor: Sekiguchi

Comments: From a 55-year old oriantal male.

Sterility: Tests for Mycoplasma, bacteria and fungi were negative

Biosafety Level: 1

ATCC number: HTB-103
