the seed lectin is used in hospitals worldwide as a liver fibrosis biomarker.
when your liver gets damaged from hepatitis B/C, fatty liver, or alcohol, your liver cells secrete a glycoprotein called Mac-2 binding protein (M2BP). the wisteria lectin specifically binds to the abnormal glycosylated version of this protein, which only appears when your liver is actively fibrosing (scarring).
used to track liver damage progression without having to do a needle biopsy.
