簡單介紹

L10BIOBR-MAPKK細胞應如何避免細胞污染,細胞污染的種類可分成**、酵母菌、霉菌、病毒和霉?jié){菌。主要的污染原因為無菌操作技術不當、操作室環(huán)境不佳、污染之血清和污染之細胞等。嚴格之無菌操作技術、清潔的環(huán)境、與品質良好之細胞來源和培養(yǎng)基配制是減低污染之*好方法。L10BIOBR-MAPKK細胞何時須更換培養(yǎng)基?視細胞生長密度而定,或遵照細胞株基本數(shù)據(jù)上之更換時間,按時更換培養(yǎng)基即可。

Comments: L10BIOBR-MAPKK細胞The L10BIOBR-MAPKK cell line (ATCC CRL-2771) was derived by infecting the immortalized murine melanocyte cell line, L10BIOBR, with pBABE which encodes a constitutively active MAPKK. The vector contains the SV40 viral DNA sequences and the puromycin resistance gene. The cells were selected in medium containing puromycin.The introduction of the MAPKK gene into melanocytes leads to tumorigenesis in nude mice, activation of the angiogenic switch and increased production of the proangiogenic factor, vascular endothelial growth factor (VEGF), and matrix metalloproteinases (MMPs). Activation of MAP kinase signaling may be an important pathway involved in melanoma transformation. Inhibition of MAP kinase signaling may be useful in the prevention and treatment of melanoma. The L10BIOBR-MAPKK cell line and the corresponding negative control, L10BIOBR-GFP (CRL-2770), are a model for melanoma tumorigenesis and signal transduction [PubMed: 12514183].

Propagation: ATCC complete growth medium: Ham's F10 medium supplemented with 50 ng/ml TPA (Sigma Catalogue No. P-8139) and 7% horse serum

Atmosphere: air, 95%; carbon dioxide (CO2), 5%

Temperature: 37.0°C

Subculturing: Protocol:

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: L10BIOBR-MAPKK細胞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.

An inoculum of 5 X 10(3) to 7 X 10(3) viable cells/sq. cm. is recommended.

Incubate cultures at 37?C.


Interval: Subculture when cells reach a concentration of 4 X 10(4) cells/sq. cm.

Subcultivation Ratio: A subcultivation of 1:6 to 1:8 is recommended

Medium Renewal: Two to three times weekly

Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO

Storage temperature: liquid nitrogen vapor phase

Doubling Time: 24 hours

Related Products: recommended serum:ATCC 30-2040

derived from same cell line:ATCC CRL-2770
