Rabbit Polyclonal Antibody to UCHL1
Cat# RPCA-UCHL1
$120.00 – $800.00
Ubiquitin C-terminal hydrolase 1 (UCHL1) is an extremely abundant protein of brain, where it is localized only in neurons. It was originally named PGP9.5 and discovered as a major protein spot on 2D gels of brain extracts which was absent on similar gels of other tissues (1). Later it was found that the PGP9.5 protein was an enzyme which could cleave ubiquitin monomers from ubiquitin conjugates and polyubiquitin chains, resulting in recycling of ubiquitin monomers and the renaming of PGP9.5 to UCHL1 to reflect this enzymatic activity (2). UCHL1 is an essential enzyme and defects in UCHL1 protein expression are involved in Parkinson’s disease (PD) and other more serious disease states (3-6). Genetic studies defined defects in the PARK5 gene as causative of PD in a German family, the PARK5 gene encoding UCHL1 (7). In addition UCHL1 may be released into cerebrospinal fluid (CSF) and blood following CNS damage and disease resulting in neuronal loss. As a result detection of this protein may give information about CNS compromise and recovery (8,9).
The RPCA-UCHL1 antibody was made against full length recombinant human UCHL1 expressed in and purified from E. coli and can be used to identify neurons and their processes in culture or in sections. The immunogen used to generate this antibody is available from EnCor, PROT-r-UCHL1. The antibody works cleanly on appropriate lysates of cell and tissues. Considerable interest has been focused on the detection of UCHL1 in the blood and CSF of patients with traumatic injuries to the brain or spinal cord. This antibody has been widely used as both a capture and a detection reagent in ELISA type assays for measuring UCHL1 levels in blood and CSF samples. In addition EnCor supplies a widely used mouse monoclonal antibody to UCHL1, MCA-BH7, and also a chicken polyclonal CPCA-UCHL1. We also supply an ELISA kit for the detection of UCHL1 in blood, CSF and other biological fluids, ELISA-UCHL1. Mouse select image at left for larger view.
Chromogenic immunostaining of a formalin fixed paraffin embedded human cerebellum section with rabbit pAb to UCHL1, RPCA-UCHL1, dilution 1:2,000 detected with DAB (brown) using the Vector Labs ImmPRESS method and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. The RPCA-UCHL1 antibody specifically labels neuronal cells throughout the brain. This antibody performs well in testing with both 4% PFA and standard NBF fixed rat, mouse, and human tissues. Mouse select image for larger view.
