H9c2（2-1）大鼠心肌細胞的介紹

該細胞由Kimes B和Brandt B從BD1X大鼠胚胎心臟組織的克隆細胞株亞克隆得到；表現出許多骨骼肌的特性。這個細胞株中的成肌細胞能融合形成多核的肌管，并對乙酰膽堿的刺激發生反應。如果培養基中的血清濃度下降到1%，融合很快發生。
動物種別：大鼠。組織來源：心臟，心肌層。形態：成肌細胞
DMEM高糖培養基（GIBCO,貨號11995065）+10%進口胎牛血清。
凍存條件：培養液+10%DMSO

Applications: transfection host （Roche FuGENE® Transfection Reagents） 
Receptors: acetylcholine, expressed 
Age:  embryo  
Comments: H9c2（2-1） is a subclone of the original clonal cell line derived from embryonic BD1X rat heart tissue by B. Kimes and B. Brandt and exhibits many of the properties of skeletal muscle. 
Myoblastic cells in this line will fuse to form multinucleated myotubes and respond to acetylcholine stimulation. 
Fusion occurs faster if the serum concentration in the medium is reduced to one percent. 
Propagation:  ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's 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%.
Atmosphere: air, 95%; carbon dioxide （CO2）, 5% 
Temperature: 37.0°C ?H9c2（2-1） 大鼠心肌細胞
Subculturing:  Protocol: The myoblastic population will become depleted rapidly if the cultures are allowed to become confluent.
To prevent loss of myoblastic cells, cultures should be subcultured before they become confluent, and the line should be recloned periodically with selection for myoblastic cells.

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 which 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.

Subc*tion Ratio: A subc*tion ratio of 1:2 to 1:4 is recommended 
Medium Renewal: Every 2 to 3 days 
Preservation:  Freeze medium: Complete growth medium supplemented with 5% （v/v） DMSO 
Storage temperature: liquid nitrogen vapor phase 
Related Products: Recommended medium （without the additional supplements or serum described under ATCC Medium）:ATCC 30-2002
recommended serum:ATCC 30-2020   ?H9c2（2-1） 大鼠心肌細胞
