编号:TS212892

品牌:Testobio

产品名称：	3A(tPA-30-1)
商品货号：	TS212892
Organism：	Homo sapiens, human
Tissue：	placenta
Cell Type：	SV40 transformed
Product Format：	frozen
Morphology：	epithelial
Culture Properties：	adherent
Biosafety Level：	2 xa0Cells contain polyomavirus DNA sequences 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.
Applications：	The cells express the transformed phenotype at the permissive temperature (33C) and the non-transformed phenotype at the non-permissive temperature (40C).
Storage Conditions：	liquid nitrogen vapor phase
Karyotype：	This is a hypodiploid human cell line with the modal chromosome number of 42 occurring in 34% of cells. However, cells with 44 chromosomes also occurred at a high frequency (26%). Most cells contained 41-45 chromosomes. Cells having a higher ploidy occurred at 20.7%, which is very high. Most cells averaged five or six marker chromosomes, none of which appeared twice in the cells examined. No chromosomes were paired consistently.
Genes Expressed：	At 40°C the cells synthesize human chorionic gonadotropin (hCG) and alkaline phosphatase
Cellular Products：	at 40C the cells synthesize human chorionic gonadotropin (hCG) and alkaline phosphatase
Comments：	The cells are transformed by SV40 ts30. The cells express the transformed phenotype at the permissive temperature (33C) and the non-transformed phenotype at the non-permissive temperature (40C). The line has a limited life expectancy of 15 to 18 passages before entering the crisis stage.
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. Remove and discard culture medium. 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. 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 33°C to facilitate dispersal. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Incubate cultures at 33°C to 34°C. Normal placental functions are expressed when the cells are incubated at the restrictive temperature (40°C). Subcultivation Ratio: 1:2 to 1:4 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: 37°C Atmosphere: Air, 95%; Carbon dioxide (CO₂), 5%
STR Profile：	Amelogenin: X CSF1PO: 10,12 D13S317: 11 D16S539: 9,12 D5S818: 11,13 D7S820: 10 THO1: 9,9.3 TPOX: 8,11 vWA: 16,17
Name of Depositor：	J Chou
Deposited As：	Homo sapiens
Passage History：	The line has a limited life expectancy of 15 to 18 passages before entering the crisis stage.
