Age 100 days
Gender male
Strain C3H/An
Applications This cell line can be used for toxicity testing.
This cell line is a suitable transfection host.
Storage Conditions liquid nitrogen vapor phase
Karyotype modal chromosome number = 66; range = 65 to 68. There were approximately 20 to 30 marker chromosomes present in each metaphase spread. A high percentage of those markers were common to most analyzed cells. A long metacentric chromosome with secondary constriction was noted in 77/100 cells. Note: Cytogenetic information is based on initial seed stock at ATCC. Cytogenetic instability has been reported in the literature for some cell lines.

Derivation The parent L strain was derived from normal subcutaneous areolar and adipose tissue of a 100-day-old male C3H/An mouse.
NCTC clone 929 (Connective tissue, mouse) Clone of strain L was derived in March, 1948. Strain L was one of the first cell strains to be established in continuous culture, and clone 929 was the first cloned strain developed.
Clone 929 was established (by the capillary technique for single cell isolation) from the 95th subculture generation of the parent strain.

Complete Growth Medium The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: horse serum to a final concentration of 10%.
Subculturing Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes. Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product.
1.Remove and discard culture medium.
2.Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
3.Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37℃ to facilitate dispersal.
4.Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
5.Add appropriate aliquots of the cell suspension to new culture vessels.
6.Incubate cultures at 37℃.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:8 is recommended
Medium Renewal: 2 to 3 times per week
Cryopreservation Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Culture Conditions Atmosphere: Air, 95%; carbon dioxide (CO2), 5%
Temperature: 37℃
