Leucine-rich alpha-2-glycoprotein (encoded by LRG1) is a serum biomarkerof inflammatory bowel disease and various autoimmune diseases. LRG1 can bind to TGF-beta1 (KD: 2.32 µM) and modulate the TGFbeta pathway[1][2][3]. LRG1 Protein, Human (HEK293, Fc-His) is the recombinant human-derived LRG1 protein, expressed by HEK293 , with C-hFc, C-6*His labeled tag.
