Detection of Human, Mouse, and Rat UCH-L1/PGP9.5 by Western Blot. Western blot shows lysates of A172 human glioblastoma cell line, Neuro‑2A mouse neuroblastoma cell line, PC‑12 rat adrenal pheochromocytoma cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human/Mouse/ Rat UCH-L1/PGP9.5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6007) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for UCH-L1/PGP9.5 at approximately 29 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Human and Mouse UCH‑L1 by Simple WesternTM. Simple Western lane view shows lysates of A172 human glioblastoma cell line and Neuro‑2A mouse neuroblastoma cell line, loaded at 0.2 mg/mL. A specific band was detected for UCH‑L1/ PGP9.5 at approximately 30 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human/Mouse/Rat UCH‑L1/PGP9.5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6007) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Deubiquitination is a critical regulatory process in the ubiquitin-proteasome pathway (1). Ubiquitin C-terminal hydrolases (UCHs) are a family of cysteine proteases that catalyze the hydrolysis of a peptide bond at the C-terminal glycine of ubiquitin. Members of the UCH family have been implicated in a number of human diseases, including neurodegenerative diseases and cancers (2). Mutations of the UCH-L1 gene and alterations of the protein activity have been found to be associated with several neurodegenerative disorders, including Parkinson’s, Huntington’s and Alzheimer’s diseases (3). It is also implicated in cancer tumorigenesis, including lung, breast, liver, kidney, colorectal and ovarian cancers (4‑8). UCH-L1 is thought to be a tumor suppressor and biomarker for hepatocellular carcinoma and other digestive tumors.
