UCH-L1/PGP9.5 Antibody (972119) [Unconjugated]

Western blot shows lysates of A172 human glioblastoma cell line, Neuro-2A mouse neuroblastoma cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.1 µg/mL of Mouse Anti-Human UCH-L1/PGP9.5 Monoclonal Antibody (Catalog # MAB60072) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for UCH-L1/PGP9.5 at approximately 26 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

UCH-L1/PGP9.5 was detected in immersion fixed A172 human glioblastoma cell line using Mouse Anti-Human UCH-L1/PGP9.5 Monoclonal Antibody (Catalog # MAB60072) at 0.3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

UCH-L1/PGP9.5 was detected in immersion fixed paraffin-embedded sections of human brain (caudate nucleus) using Mouse Anti-Human UCH-L1/PGP9.5 Monoclonal Antibody (Catalog # MAB60072) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

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 31 kDa (as indicated) using 1 µg/mL of Mouse Anti-Human UCH-L1/PGP9.5 Monoclonal Antibody (Catalog # MAB60072) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background

UCH-L1 (ubiquitin carboxyterminal hydrolase isozyme 1; also PGP9.5) is a 24-27 kDa member of the peptidase C12 family of enzymes. It shows restricted expression, being found in neurons and oocytes. UCH-L1 has dual enzymatic activity. As a monomer, it is a ubiquitin hydrolase that removes ubiquitin from modified proteins; as a homodimer, it acts as a ligase that creates ubiquitin dimers. In neurons, UCH-L1’s most important role appears to be that of generating free ubiquitin. Human UCH-L1 is 223 amino acids (aa) in length. It is O-glycosylated, ubiquitinated, and farnesylated; when farnesylated, it becomes associated with cell membranes. Three potential splice forms are reported. One shows a two aa substitution for aa 12-15, a second contains an alternative start site at Met82, and a third shows the same start site coupled with a deletion of aa 138-153. Full-length human UCH-L1 shares 95% aa identity with mouse UCH-L1.
