GC-2spd(ts)

规格:

货期:

编号:TS212126

品牌:Testobio

产品名称：	GC-2spd(ts)
商品货号：	TS212126
Organism：	Mus musculus, mouse
Cell Type：	spermatocyte; SV40 large T antigen transfected
Product Format：	frozen
Morphology：	epithelial
Culture Properties：	adherent
Biosafety Level：	2 CELLS CONTAIN PAPOVAVIRUS 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.
Age：	6 weeks
Gender：	male
Strain：	BALB/c
Applications：	This cell line may be useful for the study of spermatogenesis.
Storage Conditions：	liquid nitrogen vapor phase
Derivation：	GC-2spd(ts) was established by stable cotransfection of freshly isolated spermatocytes with the SV40 large T antigen gene (pSV3neo, see ATCC 37150) and a temperature sensitive mutant of the p53 tumor suppressor gene (LTRp53cG9). Cells were selected with G-418, cultivated for 6 months and single cell cloned three times by limiting dilution. No clonal proliferation was observed in soft agar cultures, indicating that these cells were immortalized but not transformed.
Clinical Data：	male
Comments：	The cells have lost their differentiation potential, and are currently arrested at a premeiotic stage.
Complete Growth Medium：	The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles Medium, Catalog No. 30-2002. 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 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 mMxa0EDTA 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 37°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 37°C Subculture Ratio: 1:5 to 1:7 Medium Renewal: 2 to 3 times a week. 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.
