LIF與ESGRO在細(xì)胞培養(yǎng)中的特點(diǎn)
點(diǎn)擊次數(shù)：820 發(fā)布時(shí)間：2012-2-29
LIF與ESGRO®用于干細(xì)胞培養(yǎng)的優(yōu)勢(shì)：
1.適合胚胎干細(xì)胞、神經(jīng)干細(xì)胞、造血干細(xì)胞及間充質(zhì)干細(xì)胞等多種干細(xì)胞培養(yǎng)
2.消除了飼養(yǎng)層細(xì)胞的干擾與污染
3.一致地抑制ES細(xì)胞的分化
4.減少了支原體污染的危險(xiǎn)
5.方便使用的包裝形式

Specific Activity:
ESGRO® is assessed both on ES {embryonic stem} cells （D3 & MBL-1） and on murine M1 myeloid leukemic cells（4）. A standard of 50 Units is defined as the concentration of ESGRO®, in 1.0mL of tissue culture medium, that induces the differentiation of 50% of M1 colonies（4）. 10E7 units is equivalent to approximay 100 μg of pure protein, and is sufficient to treat 10L of ES cell culture media.
Embryonic Stem Cell Assay: Differentiation inhibition at 1000 units/mL Murine myeloid leukemic, M1 Assay: Specific Activity >/= 108 units/mg

High Quality. Validated. Reliable.
EmbryoMax ESGRO® （LIF）
Description:
ESGRO® （LIF）
Trade Name:
Chemicon （Millipore）
Qty/Pk:107 units
Key Applications:
Stem Cell Culture
Application Notes:
Applications for ESGRO® include use as a reagent for the in vitro maintenance of the pluripotential phenotype of murine ES cells.
SUGGESTED PROTOCOLS:
ES Cells: In D3 and MBL-1 pluripotential ES cell cultures it is routinely found that 1000 U of ESGRO® per 1.0 mL of tissue culture media is required to maintain ES cells with a stem cell phenotype. Similar concentrations of mLIF have also been used for germline transmission of genetically altered ES cells（E3）.
At the recommended concentration 107 units of ESGRO® is sufficient for 10.0 L of tissue culture media and 106 units of ESGRO® is sufficient for 1.0 L of tissue culture media.
