  • Synonym
    LIFR,CD118,FLJ98106,FLJ99923,SJS2,STWS,SWS
  • Source
    Human LIF R, Fc Tag (LIR-H4252) is expressed from human 293 cells (HEK293). It contains AA Gln 45 - Ser 833 (Accession # P42702-1).
    Predicted N-terminus: Gln 45
  • Molecular Characterization
    Online(Gln 45 - Ser 833) P42702-1

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 115.5 kDa. The protein migrates as 140-190 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Background
    Leukemia inhibitory factor receptor is also known as LIFR; CD118; FLJ98106; FLJ99923; LIF-R; SJS2; STWS; SWS, is the receptor for leukemia inhibitory factor (LIF). The leukemia inhibitory factor is a polyfunctional cytokine that affects the differentiation, survival, and proliferation of a wide variety of cells in the adult and the embryo. LIF action appears to be mediated through a high-affinity receptor complex composed of a low-affinity LIF binding chain (LIF receptor) and a high-affinity converter subunit, gp130. Both LIFR and gp130 are members of a family of cytokine receptors that includes components of the receptors for the majority of hematopoietic cytokines and for cytokines that affect other systems, including the ciliary neurotrophic factor, growth hormone and prolactin Defects in LIFR are the cause of Stueve-Wiedemann syndrome (SWS), a severe autosomal recessive condition and belongs to the group of the bent-bone dysplasias.
