F98 EGFR 大鼠恶性胶质瘤细胞

F98 EGFR

Product category	Animal cells
Synonyms	F98(EGFR)
Organism	Rattus norvegicus, rat
Cell type	-
Morphology	glial
Tissue	Brain
Disease	Undifferentiated Malignant Glioma
Applications	3D cell culture Neuroscience

Characteristics

Growth properties	Adherent
Derivation	The F98 EGFR was produced by transfecting parental F98 rat glioma cells with an expression vector containing human, wildtype EGFR cDNA.
Population doubling time	-
Age	20 days gestation
Tumorigenic	Yes; tumorigenic in syngeneic Fischer rats
Expression markers	Epidermal growth factor receptor (EGFR), expressed
Comments	F98 EGFR cells express approximately 5 x 105 non-functional EGFR sites per cell compared with an undetectable number of EGFR sites on F98 parental cells.

Handling information

Unpacking and storage instructions	Check all containers for leakage or breakage. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below -130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete medium	The base medium for this cell line is formulated Dulbecco's Modified Eagle's Medium. To make the complete growth medium, add the following components to the base medium: 0.2 mg/ml G -418 fetal bovine serum to a final concentration of 10%
Temperature	37°C
Atmosphere	95% Air, 5% CO₂
Handling procedure	To insure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C. Storage at -70°C will result in loss of viability. Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water. Thawing should be rapid (approximately 2 minutes). Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions. Transfer the vial contents to a centrifuge tube containing 9.0 mL complete culture medium and spin at approximately 125 x g for 5 to 10 minutes. Resuspend cell pellet with the recommended complete medium (see the specific batch information for the culture recommended dilution ratio) and dispense into a 25 cm2 or a 75 cm2 culture flask. It is important to avoid excessive alkalinity of the medium during recovery of the cells. It is suggested that, prior to the addition of the vial contents, the culture vessel containing the complete growth medium be placed into the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6). Incubate the culture at 37°C in a suitable incubator. A 5% CO2 in air atmosphere is recommended if using the medium described on this product.
Subculturing procedure	Volumes used in this protocol are for 75 cm2 flasks; 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 Ca++/Mg++ free Dulbecco's phosphate-buffered saline (D-PBS) or 0.05% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and inspect 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. Note: If cells are cultured continuously, add 0.6 mg/mL G-418 to the complete growth medium for a passage about once a month. Subcultivation ratio: A subcultivation ratio of 1:6 to 1:10 is recommended. Medium renewal: Every 2 to 3 days.
Reagents for cryopreservation	Complete growth medium supplemented with 10% (v/v) DMSO.
