Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

To express the recombinant Human FGL1 protein in mammalian cells, a DNA fragment encoding the Human FGL1 protein (23-312aa) is inserted into a plasmid vector and transferred to the mammalian cells. Cells containing the plasmid are screened, cultured, and induced to express the FGL1 protein. The protein carries a C-terminal hFc-Myc tag. Lysing the cells allows for the collection of the recombinant Human FGL1 protein, which is purified through affinity purification and then identified through SDS-PAGE and subsequent staining of the gel with Coomassie Brilliant Blue. The purity of the recombinant Human FGL1 protein obtained is greater than 85%.

Target Background

Function
Immune suppressive molecule that inhibits antigen-specific T-cell activation by acting as a major ligand of LAG3. Responsible for LAG3 T-cell inhibitory function. Binds LAG3 independently from MHC class II (MHC-II). Secreted by, and promotes growth of, hepatocytes.
Gene References into Functions
  1. FGL1 promotes invasion and metastasis of gastric cancer and is associated with poor prognosis. PMID: 29845203
  2. findings highlight the crucial role of HFREP1 in insulin resistance and diabetes, and provide a potential strategy and biomarker for developing therapeutic approaches to combat these diseases. PMID: 27221093
  3. Hepassocin plays an important role in non-alcoholic fatty liver disease and induces hepatic lipid accumulation through an ERK1/2-dependent pathway. PMID: 23792031
  4. Here, the application of small ubiquitin-related modifier (SUMO) fusion technology in combination with four different chaperone teams on the soluble expression of recombinant HPS protein was explored and analyzed. PMID: 24084006
  5. Findings suggest that hepassocin promotes hepatic cell line L02 cells proliferation via an autocrine mechanism and inhibits HCC cells proliferation by an intracrine pathway. PMID: 21618590
  6. data demonstrated that liver-specific gene LFIRE-1/HFREP-1 was frequently downregulated and might possess growth suppressor activity in HCC PMID: 14981537
  7. HFREP-1 in plasma almost completely bound to the fibrin matrix during clot formation PMID: 16996032
  8. The enhancement of FGL1 levels in vitro by IL-6 and its induction after turpentine oil injection suggest that it is an acute phase reactant. PMID: 18039467
  9. HNF1 binding site and HNF1alpha are critical to liver-specific expression of HPS, and down-regulation or loss of HNF1alpha causes, at least in part, the transcriptional down-regulation of HPS in HCC. PMID: 19304666
