COLO 205 Cell Line | CL-0066

COLO 205 Cell Line | CL-0066 | Gentaur US, UK & Europe Disrtribition

Media: CM-0066

Organism: Homo sapiens, Human

Application: Transfection host.

Background: The line was derived from tissue from the same patient as COLO 201. The cells are CSAp negative(CSAp-). The cells are positive for keratin by immunoperoxidase staining. COLO 205 cells express a 36000 dalton cell surface glycoprotein related to the GA733-2 tumor associated antigen.

Age: 70 years

Tissue: Colon, derived from metastatic site: ascites

Morphology: Epithelial

Growth Properties: Mixed, Adherent And Suspension

Doubling Time: ~25 hours

Biosafty: 1

Medium: RPMI-1640(PM150110)+10% FBS+1% P/S(PB180120)

Subculturing: Remove and discard culture medium. These cells grow as a mixture of floating and adherent cells. Sometimes many cells are floating, they can be harvested by centrifugation of medium instead of discarding it. Add 1.0 to 2.0 mL of 0.25% (w/v) Trypsin-0.53mM EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 2 to 3 minutes). Add 4.0 to 6.0 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 37°C.

Ratio: 1:2 to 1:4

Renewal: Every 2 to 3 days

Cryopreservation: Freeze medium: 60% Basal medium+30% FBS+10% DMSO Storage temperature: Liquid nitrogen vapor phase

Culture Conditions: Atmosphere: Air, 95%; CO2, 5% Temperature: 37℃

Effects: Yes, in nude mice. Tumors developed within 21 days at 100% frequency(5/5) in nude mice inoculated subcutaneously with 10^7 cells.

Duration: N/A

Lead Time: 3-5 days
