产品简介
购买须知
产品名称: M3WT5
商品货号: TS211560
Organism: Cricetulus griseus, hamster, Chinese
Tissue: ovary
Product Format: frozen
Morphology: epithelial
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.

Gender: female
Applications:
The M3WT5 cell line was derived by transfecting CHO-K1 cells (ATCC CCL-61) with the pSVL expression vector containing the gene for the rat m3 muscarinic acetylcholine receptor.
Storage Conditions: liquid nitrogen vapor phase
Derivation:
The M3WT5 cell line was derived by transfecting CHO-K1 cells (ATCC CCL-61) with the pSVL expression vector containing the gene for the rat m3 muscarinic acetylcholine receptor.
Clinical Data:
female
Receptor Expression:
acetylcholine, muscarinic m3
Comments:
The M3WT5 cell line was derived by transfecting CHO-K1 cells (ATCC CCL-61) with the pSVL expression vector containing the gene for the rat m3 muscarinic acetylcholine receptor.
The resulting cells were co-transfected with pMSVNeo and selected for growth in medium containing 0.5 mg/ml G418.
M3WT5 cells are reported to express 690 fmol of receptor protein per mg of membrane protein.
Complete Growth Medium: Hams F12 medium with 0.05 to 0.1 mg/ml G418, 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 with Ca++/Mg++ free Dulbeccos phosphate-buffered saline (D-PBS) or 0.25% (w/v) Trypsin-0.53 mM 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 1:8
Medium Renewal: Every 2 to 3 days

Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapterxa013 in Culture of Animal Cells, a Manual of Basic Technique by R. Ian Freshney,xa05th edition, published by Wiley-Liss, N.Y., 2005.

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: 37°C
Atmosphere: Air, 95%; Carbon dioxide (CO2), 5%
