Cytogenetic Analysis: LS513細(xì)胞Two stem lines could be distinguished. The main one was represented in 65% of the cells, with a modal number of 51,XY and 3 markers, M1 - der(1)t(1;15), M2 - der(2)t(2;3)der(3)t(2;3), M3, and a monosomy 15., The second stem line had a modal chromosome number of 52,XY and presented M2 and M3 plus an isochromosome for the long arm of chromosome 1 called M4., A trisomy 5,7, a tetrasomy 13, and a monosomy 2 and 3 were present in all of the cells analyzed; the line did not exhibit monosomy 15.
Age: 63 years
Gender: male
Ethnicity: Caucasian
Comments: LS513 is a colorectal carcinoma cell line isolated in 1985 from a primary tumor biopsy from a 63 year old Caucasian male patient diagnosed with a Dukes' C mucin secreting cecal tumor located at the Bauhin valve.
Approximately 50% of LS513 cells express surface carcinoembryonic antigen (CEA).
LS513 cells express the major histocompatibility (MHC) class I antigens HLA and beta 2 microglobulin.
MHC class II antigens (HLA-DR, DQ, and DP were not detected).
TGF beta-1 is inhibitory for proliferation of LS513 cells, whereas TGF beta-2 has no effect on the growth of these cells.
LS513 cells are 100-fold less sensitive to TGF beta-1 than the LS1034 (ATCC CRL-2158) cell line.
LS513 cells are multidrug resistant (MDR) and are tumorigenic in nude mice.
Colony forming efficiency was 30% in methylcellulose.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing: Subcultivation Ratio: LS513細(xì)胞A subcultivation ratio of 1:3 to 1:4 is recommended
Medium Renewal: Twice per week
Remove spent medium, add fresh 0.25% trypsin, 0.03% EDTA solution, rinse and remove trypsin.
Add fresh trypsin solution (1 to 2 ml) and let the culture sit at room temperature (or at 37C) until the cells detach.
Add fresh medium, aspirate and dispense into new flasks.
Preservation: Freeze medium: 50% Culture Medium + 40% FBS + 10% DMSO
Storage temperature: liquid nitrogen vapor phase
Doubling Time: 25 hrs
