      DescriptionESGRO® Leukemia Inhibitory Factor (LIF), 1 million units/1 mL
      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.
      Alternate Names

      • mLIF
      Background InformationMouse Leukemia Inhibitory Factor (LIF, mLIF) promotes self-renewal and long-term maintenance of pluripotent mouse embryonic stem (ES) and induced pluripotent stem (iPS) cells by suppressing spontaneous differentiation.

      FormatPurified
      PresentationESGRO® Supplement is supplied in liquid form as 106 Units in 1.0 mL of phosphate buffered saline with 1% w/v bovine serum albumin BSA as a carrier for stability.
      Applications
      ApplicationThe ESGRO Leukemia Inhibitory Factor (LIF) supplement is an optimized formulation of recombinant mouse LIF (mLIF) for in vitro maintenance of mouse ES and iPS cells. Each vial contains 10^6 units.
      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 of 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® Supplement 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
      Concentration1 million units/1 mL
      PurityThe active component mLIF has been shown to be >95% pure by SDS-PAGE. ESGRO® 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). 10<sup>6</sup> units is equivalent to approximately 10 μg of pure protein, and is sufficient to treat 1L 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.

      Preguntas frecuentes

      PreguntaRespuesta
      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 settings Recommendation: Ensure that the CO2 incubator readings are correct at 37oC and 5% CO2.
      Cause of Differation: Concentration of ES cells Recommendation: 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 of Differation: Gelatin Recommendation: 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 number Recommendation: 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.
      Cause for the lack of chimeras: Time taken prior to microinjection Recommendation: 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.
