Mouse FGL1 Protein, Fc Tag
Synonym
FGL1, Hepassocin, HP-041, HFREP-1, LFIRE-1, HFREP1
Source
Mouse FGL1, Fc Tag (FG1-M5258) is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Ile 314 (Accession # Q71KU9-1).
Predicted N-terminus: Pro
Molecular Characterization

This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 60.5 kDa. The protein migrates as 60-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC 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 with trehalose as protectant.

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.
