Anti-FGL1 Antibody

The primary antibody from Antibodies.com targets FGL1 (Fibrinogen-like protein 1), a 312-amino-acid hepatocyte-secreted glycoprotein also known as Hepassocin. FGL1 has drawn significant attention in cancer immunotherapy research following its identification as a major functional ligand for LAG-3 (Lymphocyte Activation Gene-3), an inhibitory immune checkpoint receptor expressed on activated T cells.

This Rabbit polyclonal IgG reagent is unconjugated and validated for Western Blot applications, with reactivity demonstrated against Human, Mouse, and Rat samples. It is supplied as 50 µl of liquid and should be stored frozen at -20 °C in working aliquots to limit freeze-thaw cycles. Researchers investigating hepatocellular carcinoma, glioblastoma, and LAG-3 pathway biology commonly use this antibody to characterize FGL1 expression in cell lysates and tissue homogenates.
