Biosafety Level |
1
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
Age |
neonatal |
Applications |
16Y, S16 (ATCC CRL-2941) and S42 (ATCC CRL-2942) cells should be useful for investigating the cell biology of MAG and other myelin-related components as the levels of MAG expression in the three lines are inversely related to their rates of proliferation. |
Storage Conditions |
liquid nitrogen vapor phase |

Derivation |
The S16Y cell line arose spontaneousely from a passage of the S16 (ATCC CRL-2941), a line that was derived from a primary culture of Schwann cells and was immortalized by repetitive passaging. |
Antigen Expression |
Myelin-associated glycoprotein (MAG), not expressed Galactocerebroside (GalC), not expressed P0 glycoprotein, not expressed |
Genes Expressed |
Myelin-associated glycoprotein (MAG), not expressed,Galactocerebroside (GalC), not expressed,P0 glycoprotein, not expressed |
Complete Growth Medium |
The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. 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 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Note: The culture flasks should be treated with 0.1mL/cm2 of flask surface area with 15 µg/mL poly-L-lysine (Sigma Cat. No. P-9155 or equivalent) for at least 2 hours at 37°C. Remove solution and rinse one time with DPBS and allow flask to air dry uncapped and standing upright in a biological cabinet for about 30 minutes before introducing cells.
- Remove and discard culture medium.
- Briefly rinse the cell layer with Ca++/Mg++ free Dulbecco's phosphate-buffered saline (DPBS) or 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
- 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°C to facilitate dispersal.
- Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
- Transfer cell suspension to a centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes. Discard supernatant.
- Resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels.
- Incubate cultures at 37°C.
Subcultivation ratio: A subcultivation ratio of 1:5 to 1:12 twice weekly is recommended.
Medium renewal: Every 2 to 3 days. |
