中文名稱:小鼠脂肪細胞
英文名稱:3T3 L1
產品規格:25cm2
本產品僅供科研使用,不得用于臨床及診斷使用!
一、組成
細胞一瓶 25cm2
細胞說明書 1份
細胞培養注意事項 1份
二、客戶自備試劑
1、PBS
2、RPMI-1640培養基+ 10%小牛血清
3、0.25% (W/V)胰蛋白酶(含0.53mM EDTA)
三、細胞背景
1、生長方式:貼壁
2、種屬:Mus musculus (mouse)
3、形態學:成纖維細胞樣
4、組織來源:胚胎
5、其他:L1是通過克隆分離得到的3T3 (swiss小白鼠)的連續亞株。 當細胞從快速分裂到長滿且接觸
抑制時,該細胞經過前脂肪向脂肪樣逆轉。 培液中,高血清含量可以促進脂肪積累
四、培養條件
1、培養基:DMEM(高糖)+10%CS
2、溫度:37.0°C
3、氣體:空氣 95%,CO2 5%
4、培養條件:細胞應培養在塑料材質的器皿中,在玻璃材質的器皿中可能生長的不是很好。每平方厘米
細胞數目能達到50000個。
五、培養方法
不能允許細胞*匯合
1、吸掉或倒掉培養瓶內培養液。
2、用0.25% (w/v)胰蛋白酶和EDTA混合液漂洗細胞層,除去培養基殘液,避免對胰蛋白酶的抑制。
3、向瓶內加入2.0-3.0ml胰蛋白酶液和EDTA混合液(以能覆蓋培養瓶底為宜),在倒置顯微鏡下觀察細
胞,直到細胞層分散。(注:為了避免細胞聚集,在細胞分散的過程中,不要晃動細胞。消化難度較大的
細胞,應放于37°C溫浴。)
4、加入6.0-8.0ml的培養基,混均細胞。
5、用計數板計數后,分別接種于新的培養瓶中(注:*接種濃度為2-3 X 10(3)細胞/平方厘米,達到
70%-80%匯合或細胞數達到5-6 X10(4)細胞/平方厘米傳代)
6、置CO2培養箱中,在37°C進行培養。
7、培養基更新:每周2-3次
六、保存方式
1、保存培養基:培養基95%,DMSO, 5%
2、保存條件:液氮

一、REAGENTS PROVIDED
Cell 25cm2
Instruction 1
Cell culture advice 1
二、 MATERIALS REQUIRED BUT NOT SUPPLIED
1、PBS
2、Complete growth medium
3、0.25% Trypsin-0.53mM EDTA
三、CELL BACKGROUND
1、Growth Properties: Adherent
2、Organism: Mus musculus (mouse)
3、Morphology: fibroblast
4、Source: Organ: embryo
6、Comments: L1 is a continuous substrain of 3T3 (Swiss albino) developed through clonal isolation. The cells
undergo a pre-adipose to adipose like conversion as they progress from a rapidly dividing to a confluent and
contact inhibited state. A high serum content in the medium enhances fat accumulation [PubMed ID:
4426090]. Tested and found negative for ectromelia virus (mousepox).
四、PROPAGATION
1、Complete growth medium: DMEM(高糖)+10%CS
2、Temperature: 37.0C
3、Atmosphere: air, 95%; carbon dioxide (CO2), 5%
4、Growth Conditions: The cells should be grown in plastic flasks, they do not grow well on some types of
glass surfaces. A saturation density of approximay 50000 cells per sq cm can be reached.
五、SUBCULTURING PROTOCOL
Never allow culture to become compley confluent.
1. Remove and discard culture medium.
2. 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.
3. 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 37C to facilitate dispersal.
4. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
5. Add appropriate aliquots of the cell suspension to new culture vessels.
The recommended inoculum is 2 to 3 X 10(3) cells/sq. cm. Subculture before cultures become 70 to 80%
confluent or when cells reach 5 to 6 X10(4) viable cells/sq. cm.
6. Incubate cultures at 37C.
Interval: Every three days
Medium renewal: 2 to 3 times per week
六、PRESERVATION
Freeze medium: culture medium 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
