LIF Protein, Mouse is a lymphoid factor involved in various neural and inflammatory processes such as the acute-phase reaction, tissue damage, and infection.


Leukemia Inhibitory Factor (LIF) has been shown to possess a remarkable variety of actions. It releases calcium from bone tissue, and is the differentiation inhibitory factor preventing spontaneous differentiation in normal embryonic stem cells[1]. Leukemia inhibitory factor (LIF) is involved in both the neural and immune responses to injury. Its levels are increased in a variety of animal and human inflammatory conditions. Administration of Leukemia Inhibitory Factor can suppress inflammatory signs in some cases, for instance after intratracheal lipopolysaccharide-induced inflammation. Leukemia Inhibitory Factor also increases corticosterone levels via the hypothalamo-pituitary-adrenal axis. Exogenously added Leukemia Inhibitory Factor induces acute phase protein expression and stimulates the production of proinflammatory cytokines and monocyte chemoattractants[2]. In the hematopoietic system, LIF induces the differentiation of certain leukemic cells and the proliferation of hematopoietic stem cells, megakaryocyte progenitor cells and DA1 cells. LIF also has activity in bone remodelling, induction of the acute phase response in hepatocytes, inhibition of adipogenesis, regulation of nerve differentiation and inhibition of kidney epithelial cell differentiation[3].

Biological Activity

1.The ED50 is <0.01 ng/mL as measured by M1 cells, corresponding to a specific activity of >1.0 × 108 units/mg.
2.Measured by its ability to induce IL-6 secretion by M-NFS-60 mouse cells. The ED50 for this effect is 2.407 ng/mL, corresponding to a specific activity is 4.15×105 U/mg.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.


Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
