Organism Cricetulus griseus, hamster, Chinese
Product Format frozen
Morphology epithelial
Culture Properties adherent
Biosafety Level 1
Gender female
Applications
PgsB-650 is a Chinese hamster ovary cell mutant deficient in galactosyltransferase I (UDP-D-galactose:xylose-1,4-D-galactosyl transferase).
The cell line was derived from CHO-K1 cells (see ATCC CCL-61) treated with mutagen (ethylmethanesulfonate) and screened for mutants defective in proteoglycan synthesis.
PgsB-650 cells have reduced levels of galactosyltransferase, and have a three-fold reduction in production of glycosaminoglycans relative to normal.
Derivation
The cell line was derived from CHO-K1 cells (see ATCC CCL-61) treated with mutagen (ethylmethanesulfonate) and screened for mutants defective in proteoglycan synthesis.
Clinical Data
female

Subculturing
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended
Medium Renewal: Every 2 to 3 days
Protocol: 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 (D-PBS) 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 37C to facilitate dispersal.
  • Add 2.0 to 3.0 ml of complete growth medium and aspirate cells by gently pipetting
  • Resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels.
  • Incubate cultures at 37C.
Cryopreservation
