Human FGL1 Protein, His Tag

  • Synonym
    FGL1,Hepassocin,HP-041,HFREP-1,LFIRE-1,HFREP1
  • Source
    Human FGL1, His Tag (FG1-H52Hy) is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Ile 312 (Accession # Q08830-1).
  • Molecular Characterization
    Online(Leu 23 - Ile 312) Q08830-1

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 36.0 kDa. The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS with Arginine, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • Background
    Fibrinogen-like protein 1(FGL1) is also known as HP-041, Hepassocin, HFREP-1, LFIRE-1. The protective effect of fibrinogen-like protein 1 (FGL1) in liver injury has previously been reported. However, studies have shown that FGL1 may be a predictor of GC patients and a target for GC therapy. Immunocytochemical studies revealed that fgl1 selectively binds to defective spermatozoa in the cauda epididymidis. Northern blot analysis and in situ hybridization demonstrated the high expression of fgl1 in the principal cells of the proximal cauda epididymidis. Immunofluorescence analysis using mouse fibrotic lung tissues suggested that fibrotic regions showed increased expressions of Gtse1 and Fgl1, Gtse1 and Fgl1 are suggested to be novel targets for radiation-induced lung fibrosis.
