      DescriptionESGRO® Recombinant Mouse LIF Protein
      OverviewThe ESGRO mouse LIF medium supplement is supplied in active units/mL for consistent performance from lot to lot. Each lot of ESGRO supplement undergoes stringent quality control testing to ensure reliable inhibition of mouse pluripotent stem cell differentiation. ESGRO mouse LIF supplement may be used for feeder based and feeder free culture of mouse embryonic stem (ES) and induced pluripotent stem (iPS) cells.

      ApplicationESGRO Leukemia Inhibitory Factor (LIF) supplement for mouse ES cell culture. Each vial contains 10^7 units/ml.
      Key Applications
      • Stem Cell Culture
      Application NotesApplications for ESGRO® Supplement 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 ESGRO® Supplement 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® Supplement is sufficient for 1.0 L of tissue culture media.
      Biological Information
      Concentration10 million units/1 mL
      PurityThe active component mLIF has been shown to be >95% pure by SDS-PAGE. ESGRO® Supplement is supplied 0.22 micron sterile filtered, and tested negative in mycoplasma tests.
      Specific ActivityESGRO® Supplement is assessed both on mouse 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® Supplement, in 1.0mL of tissue culture medium, that induces the differentiation of 50% of M1 colonies(4). 10E7 units is equivalent to approximately 100 μg of pure protein, and is sufficient to treat 10L of ES cell culture media. <br /><br />Embryonic Stem Cell Assay: Differentiation inhibition at 1000 units/mL Murine myeloid leukemic, M1 Assay: Specific Activity >/= 10<sup>8</sup> units/mg
      Entrez Gene Number
      Entrez Gene SummaryLeukaemia inhibitory factor is a cytokine that induces macrophage differentiation. Neurotransmitters and neuropeptides, well known for their role in the communication between neurons, are also capable of activating monocytes and macrophages and inducing chemotaxis in immune cells. LIF signals through different receptors and transcription factors. LIF in conjunction with BMP2 acts in synergy on primary fetal neural progenitor cells to induce astrocytes.

      Storage and Shipping Information
      Storage ConditionsESGRO® Supplement is shipped at ambient temperature. A cold pack may be included for customer relations, however it is truly not needed. Extensive stability tests have been performed with ESGRO® Supplement during development. This product is stable for at least 18 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 ESGRO® Supplement be stored at 4°C. Freeze-thawing will reduce potency. It is recommended that prior to use, ESGRO® Supplement should be diluted in sterile tissue culture media and aliquoted to a convenient concentration, then stored at 4°C. Freeze-thawing should be avoided. Product is stable for a minimum of 7 days at 37°C, 5% CO2 incubator during the culture of ES cells.

      FAQ(よくある質問と回答)

      質問回答
      Why are my mouse embryonic stem cells differentiating and what preventative measures do you recommend?Recommendation: Regular use of Penicillin / Streptomycin in media can often mask a low level contamination with agents such as mycoplasma. It is recommended to have your cell lines tested for mycoplasma on a periodic basis.
      Cause of Differation: Incubator settingsRecommendation: Ensure that the CO2 incubator readings are correct at 37oC and 5% CO2.
      Cause of Differation: GelatinRecommendation: It is preferable to use cell culture grade gelatin at all times (even if using feeder layers) as the gelatin minimises surface differences on the tissue culture plates.
      Cause for the lack of chimeras: ES cell passage numberRecommendation: In general; the best chimeras are generated from low passage number ES cells. If cell lines have been cultured for a high number of passages, it is recommended to go back to a lower passage frozen stock.

It is recommended to have your cell lines tested for mycoplasma on a periodic basis.
      Cause of Differation: Concentration of ES cellsRecommendation: Low confluency of ES cells can result in differentiation. ES cells should be plated at a minimum density of 1x106 cells / 100mm dish. Refer to the attached figures for illustrations of ES cell confluency. Refer to figs. 1, 2, 3, 4, and 5.
      Cause for the lack of chimeras: Time taken prior to microinjectionRecommendation: It is recommend that ES cells be microinjected as soon as possible after removing them from the tissue culture plates, and not left on ice or room temperature for extended periods.
