Antigen Expression:  H-2d
Strain:  BALB/c
Age:  adult
Gender:  male
Comments:  This line was established from a tumor induced by Abelson murine leukemia virus. They are negative for surface immunoglobulin (sIg-), Ia (Ia-) and Thy-1.2 (Thy-1.2) This line does not secrete detectable virus particles and is negative in the XC plaque formation assay. The cells will pinocytose neutral red and will phagocytose latex beads and zymosan. They are capable of antibody dependent lysis of sheep erythrocytes and tumor cell targets. LPS or PPD treatment for 2 days stimulates lysis of erythrocytes but not tumor cell targets. Unpublished data communicated in Feb. 2007 by Dr Janet W. Hartley, Scientist Emerita, NIAID, indicates the expression of infectious ecotropic MuLV closely related, if not identical, to the Moloney MuLV helper virus used in the original virus inoculum. The cells also express polytropic MuLV, unsurprisingly based on the mouse passage history of the virus stocks.
Propagation:  ATCC complete growth medium: Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and 4.5 g/L glucose, 90%; fetal bovine serum, 10%
Temperature: 37.0C
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Subculturing:  Protocol: Subcultures are prepared by scraping.
For a 75 cm2 flask, remove all but 10 ml culture medium (adjust amount accordingly for other culture vessels). Dislodge cells from the flask substrate with a cell scraper; aspirate and add appropriate aliquots of the cell suspension into new culture vessels.

Subcultivation ratio: A subcultivation ratio of 1:3 to 1:6 is recommended

Medium renewal: Replace or add medium 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

我就是用细胞刮把细胞刮下来,然后吹吹散就完事了,对细胞的损伤不是很大,再次铺板90%以上都能贴壁存活。

鼠巨噬细胞系 RAW 246.7养起来算是挺方便的细胞种类了.生长力较强,传代时容易消化,细胞个体小,相对数目多,生长较快,有利于实验的进行.(当然,也是不好处--不作实验的空当也需每天照顾着)

我基本上是每天都传代,传代后细胞6小时左右可贴壁.
我们实验室的传代方法是:
1.细胞长至70%~80%密度时,需要分瓶传代,将瓶中的培养基倒掉,D-Hhanks液清洗两遍
2.加入约3ml的胰酶(0.1%的浓度,不加EDTA,RAW 246.7细胞很好消化)
3.消化两分钟左右,在镜下观察细胞状态,当视野中有几个漂起的细胞,贴壁的细胞之间分开,变圆时,立即倒掉胰酶,加入适量10%血清的培基(血清一般用的是新生牛血清,培基中DMEM,1640都用过,感觉前者容易让RAW 246.7细胞长成堆,但也要看细胞的性质了)
4.轻轻吹打下细胞,一分为二,最好再在显微镜下观察一下每瓶细胞的多少,之后放入培养箱.(吹打的时候力度不要过猛,应该用培养基把细胞冲下来. andy829210推荐的拍打瓶底的方法我准备试试)

据我所知,鼠巨噬细胞系 RAW 246.7是单核-巨噬系细胞,当长的"过老"时(比如传代不及时)细胞形态发生改变,由圆形/椭圆型变成巨多变型,长出伪足,此时的细胞就不是理想的实验对象了,它对刺激会不敏感.

我正在培养鼠巨噬细胞系 RAW 246.7,不知道应该用DMEM还是1640养,而且觉得好难消化下来,请问各位战友有什么好建议的

RAW 246.7细胞真的挺好消化的,你的问题看是不是有下面的原因:
1.胰酶的配置:最好用D-Hhanks液,不含钙镁(钙镁降低胰酶的作用),至少也应该用0.1%的浓度,即0.1克胰酶定容至100ml,注意溶解充分(我们实验室通常会在4度放置过夜,第二天过滤除菌)
2.胰酶是否失效:时间过久,长时间放置在37度预热等都可能是其失效.
3.细胞性质是否发生改变:比如分化成巨噬细胞

我也是养巨噬细胞,但这个细胞是从师兄传下来的,师兄今年已经毕业了,所以也不知道他这个细胞是怎么来的,我是复苏的这个细胞,养了有一个星期了,可是细胞都长得不太好,都是一团一团的在长,不像各位大侠们发的照片的那种啊,我都要急死了,也不知道应该怎么做,我用的1640,小牛血清,请各位大侠指点一下啊,谢谢了。
