Isolation: Isolation date: 1989

Galactocerebroside (GalC)

Age: neonatal

Comments: S42細(xì)胞The S42 cell line is derived from a primary culture of Schwann cells that was immortalized by repetitive passaging. S42 is similar to S16 (ATCC CRL-2941), but it has a higher level of High Myelin-associated glycoprotein (MAG) and a longer doubling time. At high density, the S42 cells exhibit numerous processes. Both S42 and S16 cells express galactocerebroside (GalC), sulfatide and P0 glycoprotein, but little or no myelin basic protein. [16172655] [16172656]

In many respects, S42 (ATCC CRL-2942) and S16 (ATCC CRL-2941) resemble Schwann cells at an early stage in their preparation to myelinate and are useful for investigating the cell biology of MAG and other myelin-related components. [16172656]

Propagation: ATCC 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%.

Temperature: 37.0°C

Subculturing: Protocol: The culture flasks should be treated with 0.1ml/sq. cm of flask surface area with 15ug/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.

Volumes used in this protocol are for 75 sq. cm flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.

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: S42細(xì)胞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 xg 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. An inoculum of 2 X 10(4) to 4 X 10(4) viable cells/sq. cm is recommended.

Incubate cultures at 37°C. We recommend that you subculture cultures when they reach a cell concentration between 1 X 10(5) and 2 X 10(5) cells/sq. cm.

Subcultivation ratio: A subcultivation ratio of 1:3 to 1:6 twice weekly is recommended.

Medium renewal: Every 2 to 3 days

Preservation: Freeze medium: complete growth medium, 90%; DMSO, 10%

Storage temperature: liquid nitrogen vapor phase

Doubling Time: approximately 48 hours [16172656]
