產品名稱	4T1-Luc2
商品貨號	B161364
Organism	Mus musculus, mouse
Tissue	mammary
Product Format	frozen 1.0 mL
Morphology	epithelial-like
Culture Properties	adherent
Biosafety Level	2 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	This tumor produced mimics an animal stage IV human breast cancer.
Strain	BALB/cfC3H
Applications	Excellent signal/background ratio and stable Luciferase expression make this cell line ideal for in vivo bioluminescence imaging of xenograft animal model to study human cancer and monitor activity of anti-cancer drug. It also can be used in cell-based assays for cancer research.
Storage Conditions	liquid nitrogen vapor phase
Tumorigenic	Yes, tested in BALC/c mice
Comments	This luciferase expressing cell line was derived from parental line CRL-2539 by transduction with lentiviral vector encoding firefly luciferase gene (luc2) under control of EF-1 alpha promoter. This cell line was established through single cell cloning, and the cells constitutively express high levels of enzymatically active luciferase protein, which can be detected via in vitro and in vivo bioluminescence assays. The cells should be maintained in Blasticidin (8 μg/mL) containing medium in routine cell culture. It is recommended to remove Blasticidin prior to and during the experiment procedure when the cells are injected into animals in vivo, or co-cultured with other cell types in vitro.
Complete Growth Medium	The base medium for this cell line is RPMI-1640 Medium (ATCC 30-2001). To make the complete growth medium, add the following components to the base medium: Fetal bovine serum (FBS; ATCC 30-2020) to a final concentration of 10% Blasticidin to a final concentration of 8 µg/mL
Subculturing	Note: The cells should not be allowed to become confluent, subculture at 80% of confluence. Volumes used in this protocol are for 75 cm² flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning^® T-75 flasks (catalog #430641) are recommended for subculturing this product. 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 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. Cultures can be established between 2 x 10⁴ and 4 x 10⁴ viable cells/cm². Incubate cultures at 37°C. div>Interval: Maintain cultures at a cell concentration between 1 X 10⁴ and 1.5 X 10⁵ cell/cm². Subcultivation Ratio: A subcultivation ratio of 1:6 to 1:8 is recommended Medium Renewal: Every2 to 3 days
Cryopreservation	Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
Culture Conditions	Atmosphere: air, 95%; carbon dioxide (CO₂), 5% Temperature: 37°C
