產(chǎn)品名稱 UV135 (UV sensitive mutant of CHO)
商品貨號 B165915
Organism Cricetulus griseus, hamster, Chinese
Tissue ovary
Product Format frozen
Morphology epithelial-like
Culture Properties monolayer and suspension
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
UV135 is a UV sensitive line derived from AA8 (see ATCC CRL-1859).
The line is defective in nucleotide excision repair, is sensitive to bulky adduct mutagens and belongs to excision repair complementation group 5.
Storage Conditions liquid nitrogen vapor phase
Derivation
This line is a derivative of the CHO-K1 cell line (see ATCC CCL-61).
UV135 is a UV sensitive line derived from AA8 (see ATCC CRL-1859).
Clinical Data
female
Comments
This line is a derivative of the CHO-K1 cell line (see ATCC CCL-61).
UV135 is a UV sensitive line derived from AA8 (see ATCC CRL-1859).
The line is defective in nucleotide excision repair, is sensitive to bulky adduct mutagens and belongs to excision repair complementation group 5.
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 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. The suspended cells are viable and can be used to start new cultures.

  1. To subculture attached cells, briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53 mM EDTA solution to remove all traces of serum, which contains trypsin inhibitor.
  2. Observe cells under an inverted microscope until cell layer is dispersed. 
    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.
  3. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting. 
  4. Add appropriate aliquots of cell suspension to new culture vessels.
  5. Place culture vessels in incubators at 37°C.

Subcultivation Ratio: 1:4 to 1:12
Medium Renewal: Two times weekly

Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 13 in Culture Of Animal Cells: A Manual Of Basic Technique by R. Ian Freshney, 5th edition, published by Wiley-Liss, N.Y., 2005.  

Cryopreservation
