一般說明
Applications for Rat ESGRO include use as a reagent for the in vitro maintenance of rat ES cells. Studies have demonstrated that rtLIF is more effective in maintaining the undifferentiated phenotype of rat ES cells than similar concentrations of murine LIF.
Product Source: rtLIF is expressed in E. coli as a fusion protein with GST using the pGEX expression system, cleaved from GST moiety with thrombin and purified by ion-exchange chromatography.

Applications for Rat ESGRO include use as a reagent for the in vitro maintenance of rat ES cells. Studies have demonstrated that rtLIF is more effective in maintaining the undifferentiated phenotype of rat ES cells than similar concentrations of murine LIF (Takahama et al. 1998).
Rat ES Cells: RtLIF produced from a transfected cell line, has been shown to effectively maintain the undifferentiated phenotype of rat ES cells when used at a concentration of 1000-1500 units / mL (Takahama et al. 1998).
At this recommended concentration 106 units of ESGRO is sufficient for 1L of tissue culture media.

儲存和穩定性
Rat ESGRO is shipped on dry ice. This product is stable for at least 12 months from the date of manufacture, in the concentrated form or diluted in sterile tissue culture media, with no loss of activity on ES cells.
For long term storage it is recommended that Rat ESGRO concentrate be stored at -20°C.
It is recommended that prior to use, Rat ESGRO should be diluted in sterile tissue culture media and aliquoted to a convenient concentration, then stored at -20°C. Freeze thawing will reduce potency and is not recommended.

分析報告
Specific Activity: Rat ESGRO® is assessed both on murine ES {embryonic stem} cells (MBL-1) and on murine M1 myeloid leukemic cells.A standard of 50 Units is defined as the concentration of Rat ESGRO in 1.0mL of tissue culture medium that induces the differentiation of 50% of M1 colonies.106 units is equivalent to approximately 10 μg of pure protein, and is sufficient to treat 1L of ES cell culture media.Embryonic Stem Cell Assay: Differentiation inhibition at 1000 units/mLMurine myeloid leukemic, M1 Assay: Specific Activity >108 units/mg
