General description

Leukemia inhibitory factor (LIF) is a secreted pleiotropic glycoprotein which is a member of the gp130 signaling of interleukin-6 (IL-6) family cytokines. This protein was originally identified as a protein that prevented the growth of a leukemic cell line.

Biochem/physiol Actions

Leukemia inhibitory factor (LIF) suppresses the differentiation of myoblasts, and inhibits the activation of caspase-3 and blocks the reduction in Bcl-xL (B-cell lymphoma-extra large) levels, thus, preventing doxorubicin-induced apoptosis. Along with transforming growth factor β2 (TGFβ2)/fibroblast growth factor 2 (FGF2), LIF regulates nephrogenesis. It facilitates tubular regeneration following acute kidney failure. It plays a crucial role in neuroprotective pathways induced by preconditioning-induced oxidative stress. LIF is capable of maintaining the totipotency of embryonic stem cells. It is also involved in controlling the differentiation of embryonic stem cells, hematopoietic and neuronal cells.

Physical form

Sterile filtered through a 0.22 micron filter. Lyophilized from 1 x PBS, pH 7.4. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in sterile deionized water to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
