CRL-1442 BRL 3A 大鼠肝細胞 的詳細介紹

ATCC® Number: CRL-1442™

Designations: BRL 3A

Depositors: SP Nissley, MM Rechler

Biosafety Level: 1

Shipped: frozen

Medium & Serum: See Propagation

Growth Properties: adherent

Organism: Rattus norvegicus （rat）

Morphology:

Source: Organ: liver

Strain: Buffalo

Cellular Products: somatomedin like multiplication stimulating activity （MSA）

Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimay responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.

Comments: The serum-free conditioned medium from this cell line is a source of MSA. MSA is a family of polypeptides that can partially satisfy the serum reguirement of chick embryo fibroblasts. [1060]

Propagation: ATCC complete growth medium: Minimum essential medium （Eagle） with 2 mM L-glutamine and Earle's BSS adjusted to contain 1.5 g/L sodium bicarbonate, 0.1 mM non-essential amino acids, and 1.0 mM sodium pyruvate, 90%; fetal bovine serum, 10%

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

Temperature: 37.0°C

Growth Conditions: For 24 hrs after initiating culture from a thawed ampule or after subculturing, grow the cells in culture medium with 5% fetal bovine serum. After 24 hrs, the cells may be transferred to serum-free medium.

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: 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.

To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximay 125 xg for 5 to 10 minutes.Discard supernatant and resuspend cells in fresh growth medium. Add appropriate aliquots of cell suspension to new culture vessels.

Incubate cultures at 37°C.

Subc*tion Ratio: A subc*tion ratio of 1:3 to 1:6 is recommended

Medium Renewal: 2 times per week

Preservation: Freeze medium: Complete growth medium supplemented with 10% fetal bovine serum and 5% DMSO

Storage temperature: liquid nitrogen vapor phase

Related Products: Recommended medium （without the additional supplements or serum described under ATCC Medium）:ATCC 30-2003
