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.

Disease
xylosyltransferase I deficient
Gender
female
Storage Conditions
liquid nitrogen vapor phase
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
Comments

PgsA-745 is a Chinese hamster ovary cell mutant deficient in xylosyltransferase (UDP-D-xylose:serine-1,3-D-xylosyltransferase).

The cells have a defect in xylosyltransferase, the first sugar transfer in glycosaminoglycan synthesis, and do not produce glycosaminoglycans.

Complete Growth Medium
The base medium for this cell line is ATCC-formulated F-12K Medium, Catalog No. 30-2004. 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 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.

  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53% (w/v) 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°C 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°C

Subculture Ratio: 1:4 to 1:8
Medium Renewal: 2 to 3 times a week.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.
