Part of the fibrinogen protein family, FGL1 is expressed at low levels in the liver under usual conditions. By contrast, this protein is highly expressed in various types of cancers such as melanoma and prostate cancer.
According to a recent study, FGL1 protein is a hot immune inhibitory ligand of LAG-3 products. Therefore, inhibiting the interaction between FGL1 and LAG-3 would not only improve the body’s immunity but would also slow down the growth of tumors.
ACROBiosystems has developed HEK293-expressed FGL1 protein with a wide range of tags (His, Fc) and species (Mouse, Human, Cyno). The company has also developed AviTagTM biotinylated FGL1 protein that can help in developing drugs. Moreover, ACROBiosystems has validated the activity and purity of FGL1 protein and also offers protocols.

As cited above, FGL1 protein has been recognized as a hot immune inhibitory ligand of LAG-3 products.
Bioactivity of FGL1 was Validated by ELISA
Immobilized Human LAG-3, mouse IgG2a Fc tag (Cat. No. LA3-H52Aa) at 10 μg/mL (100 μL/well) can bind Biotinylated Human FGL1, Fc Tag, Avi Tag (Cat. No. FG1-H82F3) with a linear range of 0.156–1.25 μg/mL.
Immobilized Human LAG-3, mouse IgG2a Fc tag (Cat. No. LA3-H52Aa) at 20 μg/mL (100 μL/well) can bind Human FGL1, Fc Tag (Cat. No. FG1-H5253) with a linear range of 5–78 ng/mL.
Immobilized Mouse LAG-3, His Tag (Cat. No. LA3-M52H5) at 20 μg/mL (100 μL/well) can bind Mouse FGL1, Fc Tag (Cat. No. FG1-M5255) with a linear range of 0.078–1.25 μg/mL.
Immobilized Human LAG-3, mouse IgG2a Fc tag (Cat. No. LA3-H52Aa) at 5 μg/mL (100 μL/well) can bind Cynomolgus / Rhesus macaque FGL1, Fc Tag (Cat. No. FG1-C5253) with a linear range of 8–125 ng/mL.
