Comments:LS411N is a colorectal carcinoma cell line isolated in 1985 from a primary tumor biopsy of a Dukes' B, poorly differentiated cecal carcinoma.
The LS411 cell line was found to be contaminated with mycoplasma, and was passed through nude mice to clear the cells of mycoplasma.
The cells obtained after passage in nude mice are referred to as LS411N cells.
A culture submitted to the ATCC in September 1994 was found to be contaminated with mycoplasma, and progeny were cured by a 21 day treatment with BM Cycline.
Approximately 20% of LS411N cells express surface carcinoembryonic antigen (CEA).
The cells express low levels of ICAM-1 HLA class I antigen beta-2-microglobulin.
The cells secrete low levels of latent TGF-beta 1.
TGF-beta 1 and TGF beta?2 are do not inhibit the proliferation of LS411N cells.
Colony forming efficiency was 25% in methylcellulose medium.
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: Protocol: Remove medium, and rinse with 0.25% trypsin, 0.53 mM EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.Add fresh culture medium, aspirate and dispense into new culture flasks.
Subcultivation Ratio: A subcultivation ratio of 1:3 is recommended
Medium Renewal: Twice per week
Preservation: Freeze medium: Complete growth medium, 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
Doubling Time: 24 hrs
Related Products:Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001
recommended serum:ATCC 30-2020
