|Application ||WB, IHC|
|Other Accession||7345, 518731|
|Isotype||Mouse / IgG1, kappa|
|Other Names||Ubiquitin carboxyl-terminal hydrolase isozyme L1, UCH-L1, 18.104.22.168, 6.-.-.-, Neuron cytoplasmic protein 9.5, PGP 9.5, PGP9.5, Ubiquitin thioesterase L1, UCHL1|
|Storage||Store at 2 to 8°C.Antibody is stable for 24 months.|
|Precautions||PGP9.5 / UchL1 (pan-Neuronal Marker) Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Ubiquitin-protein hydrolase involved both in the processing of ubiquitin precursors and of ubiquitinated proteins. This enzyme is a thiol protease that recognizes and hydrolyzes a peptide bond at the C-terminal glycine of ubiquitin. Also binds to free monoubiquitin and may prevent its degradation in lysosomes. The homodimer may have ATP-independent ubiquitin ligase activity.|
|Cellular Location||Cytoplasm. Endoplasmic reticulum membrane; Lipid-anchor. Note=About 30% of total UCHL1 is associated with membranes in brain|
|Tissue Location||Found in neuronal cell bodies and processes throughout the neocortex (at protein level). Expressed in neurons and cells of the diffuse neuroendocrine system and their tumors Weakly expressed in ovary. Down-regulated in brains from Parkinson disease and Alzheimer disease patients|

This MAb reacts with a protein of 20-30kDa, identified as PGP9.5, also known as ubiquitin carboxyl-terminal hydrolase-1 (UchL1). Initially, PGP9.5 expression in normal tissues was reported in neurons and neuroendocrine cells but later it was found in distal renal tubular epithelium, spermatogonia, Leydig cells, oocytes, melanocytes, prostatic secretory epithelium, ejaculatory duct cells, epididymis, mammary epithelial cells, Merkel cells, and dermal fibroblasts. Furthermore, immunostaining for PGP9.5 has been shown in a wide variety of mesenchymal neoplasms as well. A mutation in PGP9.5 gene is believed to cause a form of Parkinson's disease.
