Cytogenetic Analysis: [49835]
Age: newborn
Gender: male
Comments: The line was established from skin taken from normal foreskin.
The BJ cell line has a long lifespan in comparison with other normal human fibroblast cell lines.
A frozen ampule at population doubling 2.3 was received at the ATCC in April, 2000.
These cells have a reported normal diploid karyotype at population doubling 61 but an abnormal karyotype at population doubling 82. [49835]
They are telomerase negative. [44175]
The cells may be used for stable transfection studies. [47354]
Cells from ATCC ampules have the capacity to proliferate to a maximum of 72 population doublings before the onset of senescence.
Propagation: ATCC 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: fetal bovine serum to a final concentration of 10%.
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Subculturing: Protocol:
Remove and discard culture medium.
BJ细胞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.
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.
Add appropriate aliquots of the cell suspension to new culture vessels.
Incubate cultures at 37�C.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:9 is recommended
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
recommended serum:ATCC 30-2020
