ESGRO® Leukemia Inhibitory Factor (LIF), 10 million units/1 mL
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.

Entrez Gene Summary:
Leukaemia 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.
UniProt Summary:
FUNCTION: SwissProt: P15018 # LIF has the capacity to induce terminal differentiation in leukemic cells. Its activities include the induction of hematopoietic differentiation in normal and myeloid leukemia cells, the induction of neuronal cell differentiation, and the stimulation of acute-phase protein synthesis in hepatocytes.
SIZE: 202 amino acids; 22008 Da

Presentation:
ESGRO® is supplied in liquid form as 107 Units ESGRO® in 1.0 mL of phosphate buffered saline with 1% w/v bovine serum albumin BSA as a carrier for stability.
Storage Conditions:
ESGRO®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® 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 concentrate be stored at 4°C. Freeze-thawing will reduce potency.It is recommended that prior to use, ESGRO™ should be diluted in sterile tissue culture media and aliquoted to a convenient concentration, then stored at 4°C. Freeze-thawing should be avoided.ESGRO™ is stable for a minimum of 7 days at 37°C, 5% CO2 incubator during the culture of ES cells.

Product Name:
ESGRO® (LIF)
Alternate Names:
Murine LIF
Concentration:
10 million units/1 mL
Format:
Purified
UniProt Number:
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 approximately 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
