| Karyotype | 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. |

| 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.

| 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 | Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Subculture Ratio: 1:3 to 1:4 Medium Renewal: 2 to 3 times a week.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.
