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.

Gender female
Applications
The line is useful for gene mutation assays and is the parent line for a series of repair deficient mutants (see ATCC CRL-1860, ATCC CRL-1861, ATCC CRL-1862, ATCC CRL-1865, ATCC CRL-1866 and ATCC CRL-1867).
Storage Conditions liquid nitrogen vapor phase
Karyotype chromosome number = 21
Derivation
This line is a derivative of the CHO cell line.
Clinical Data
female
Comments
This line is a derivative of the CHO cell line.
The AA8 line has 21 chromosomes and is heterozygous at the aprt locus.
The line is useful for gene mutation assays and is the parent line for a series of repair deficient mutants (see ATCC CRL-1860, ATCC CRL-1861, ATCC CRL-1862, ATCC CRL-1865, ATCC CRL-1866 and ATCC CRL-1867).
Complete Growth Medium Alpha minimum essential medium without ribonucleosides and deoxyribonucleosides, 90%; fetal bovine serum, 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-0.53mM EDTA solution to remove all traces of serum which 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.

Subcultivation Ratio: 1:4 to 1:12
Medium Renewal: Every 2 to 3 days

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.
