产品简介
购买须知
产品名称: G1B
商品货号: TS167260
Organism: Clarias batrachus, walking catfish
Tissue: gill
Product Format: frozen
Morphology: pleomorphic
Culture Properties: adherent
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: normal
Age: adult
Storage Conditions: liquid nitrogen vapor phase
Derivation:
The G1B cell line was derived from normal gill tissue taken from a healthy adult walking catfish.
Comments:
The G1B cell line was derived from normal gill tissue taken from a healthy adult walking catfish.
The cells support the in vitro growth of Amyloodinium ocellatum, a dinoflagellate that infects the gills and skin of both marine and brackish water fishes.
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%
  • 24 mM HEPES

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.
  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 25°C.

Subcultivation Ratio: 1:2 to 1:3
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.

Cryopreservation:

Complete growth medium described above supplemented with 5% (v/v) DMSO.xa0 Cell culture tested DMSO is available as ATCC Catalog No. 4-X.

Culture Conditions:
Temperature: 25°C
Atmosphere: Air, 95%; Carbon dioxide (CO2), 5%
Name of Depositor: EJ Noga
