Description: LIM 1899 is a columnar cell adenocarcinoma of the colon.



Description Key Words: Columnar cell adenocarcinoma colon



Also Known As: No other names



Organism: Human (Homo sapiens)



Strain: N/A



Tissue: Colon



Growth Properties: Adherent



Morphology: Epithelial. Cells are small rounded and grow in clusters.



Growth Medium: RPMI 1640 (with 2mM L-Glutamine + 25mM HEPES) + 10% Foetal Calf Serum (FCS) + Insulin 0.6μg/ml, Hydrocortisone 1μg/ml, 1-Thioglycerol 10μM.



Resuscitation: Remove protective cryoflex layer around the ampoule prior to thawing. Thaw the ampoule by gently agitating in a 37°C waterbath; thawing should be rapid (around 2 minutes). A centrifugation step to remove the cryoprotectant after thawing is necessary for this cell line.



Subculturing Procedure:



Medium Renewal: 3 times each week.



Subcultivation Ratio: 1:8, Seeding density 1x104 cells/cm2. Split sub confluent flasks (70-80%). Harvest the cells using 0.05% Trypsin/EDTA at 37°C for 5 minutes.



Culture Conditions: Cells maintained at 37°C and 5% CO2.



Cryoprotectant Medium: 10% DMSO + 90% FCS



Handling Procedure for Frozen Cells: Upon receipt, frozen ampoules should be transferred directly to liquid nitrogen storage without delay, if not to be used immediately. Storage at -80°C may result in loss of viability.



Additional Information: Sporadic CRC. Mutated beta-catenin and K-Ras. A33 +ve.
