Description
LRG1 Protein, Human (HEK293, His) is the recombinant human-derived LRG1 protein, expressed by HEK293, with C-6*His labeled tag.
Background
LRG1 is a member of the leucine-rich repeat sequence (LRR) family of proteins involved in protein-protein interactions, signal transduction, and cell adhesion and development. LRG1 is involved in promoting neovascularization (new blood vessel growth) by causing the switching of transforming growth factor β (TGF-β) signaling in endothelial cells. LRG1 binds to the co-receptor endorphins and promotes signaling through the ALK1-Smad1/5/8 pathway. LRG1 is involved in ovarian cancer progression by activating the FAK/AKT signaling pathway[1][2][3].
Verified Bioactivity
Measured by its binding ability in a functional ELISA. Immobilized human Cytochrome c (HY-125857) at 1 μg/mL (100 μL/well) can bind Biotinylated Human LRG1 protein. The ED50 for this effect is 5-80 ng/mL.

Product Properties
Lyophilized powder
1.Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 20 mM NaCl, pH 7.5.
2.Lyophilized from a 0.22 μm filtered solution of 20 mM Tris, 20 mM NaCl, pH 7.5.
3.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 5% trehalose.
Please refer to the lot-specific COA for specific buffer information.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
