Applications This cell line is a suitable transfection host.

This line was originally developed for use as a source of X chromosomes in a study of X inactivation, and was subsequently found to be an excellent cell culture model for the kidney proximal tubule epithelium.

The cells display a variety of receptors in culture, and have been widely used as a model for studying those receptors.


Storage Conditions liquid nitrogen vapor phase
Clinical Data
female
Receptor Expression
alpha 2 adrenergic, expressed
atrial natriuretic peptide (ANP), expressed
serotonin, expressed
parathyroid hormone (PTH), expressed
alpha 2 adrenergic; serotonin; parathyroid hormone (PTH); atrial natriuretic peptide (ANP)
Complete Growth Medium The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. 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 are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally 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 mM 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.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended
Medium Renewal: Twice per week
Cryopreservation
Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C
Name of Depositor MM Miller
