Detection of Human, Mouse, and Rat Hepassocin by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, Hepa 1‑6 mouse hepatoma cell line, and H4‑II‑E‑C3 rat hepatoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/ Mouse/Rat Hepassocin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1614) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Hepassocin homodimer at approximately 65 kDa (as indicated). Hepassocin is resistant to reducing conditions (1). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Hepassocin, also known as hepatocyte-derived fibrinogen-related protein (HFREP-1), is a liver specific secreted protein containing one fibrinogen C-terminal domain. It exists as a homodimer and is reported to have hepatocyte mitogenic activity (1).
