  • 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.
  • Tissue specificity

    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.
  • Involvement in disease

    Parkinson disease 5
    Neurodegeneration with optic atrophy, childhood-onset
  • Sequence similarities

    Belongs to the peptidase C12 family.
  • Post-translational

  • Cellular localization

    Cytoplasm. Endoplasmic reticulum membrane. About 30% of total UCHL1 is associated with membranes in brain.

  • Formalin-fixed, paraffin-embedded human pancreas tissue stained for PGP9.5 using ab15503 at 1/200 dilution in immunohistochemical analysis.

  • ICC/IF image of ab15503 stained DU145. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab15503 at 1 ug/mL overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for contacting us.

According to UniGene, the RNA for this protein can be found quite abundantly in human pancreas. Therefore, it shouldn't be a problem to find a suitable antibody which has been tested in human and IHC-P.

We have two polyclonal antibodies, which have been used in various references and Abreviews. However, only

https://www.abcam.com/index.html?datasheet=15503 (or use the following: https://www.abcam.com/index.html?datasheet=15503).

has been tested by us so far in-house in pancreas tissue.

The other antibody whith a lot of refferences and Abreviews would be

https://www.abcam.com/index.html?datasheet=10404 (or use the following: https://www.abcam.com/index.html?datasheet=10404).

If they would prefer a monoclonal antibody, I would like to suggest

https://www.abcam.com/index.html?datasheet=8189 (or use the following: https://www.abcam.com/index.html?datasheet=8189).

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your technical questionnaire. Once again I am sorry to hear that you have been having difficulties with this antibody in sheep tissue. Whilst this antibody is yet to be tested using ovine tissue it is a surprise to find that you have been obtaining correct staining in your positive and negative controls but aberrant staining that is specific to sarcocysts and not surrounding ovine tissue. I have read your technical questionnaire and you seem to have performed many of the optimisation steps that I would recommend. The fact that you are using a negative control confirms that it cannot be unquenched peroxidase activity. Furthermore given that you are blocking in goat serum the non-specific staining cannot be attributable to the secondary antibody binding to the sarcocyst cells. The only recommendation that I could recommend is to dilute the antibody further and perform longer incubations of the antibody. This may improve the specificity. It may be that this antibody demonstrated some reactivity against an ovine protein ONLY expressed in sarcocysts and therefore is showing an interesting staining pattern as a consequence. I am sorry that I cannot be of more assistance.

Thank you for your enquiry and for completing our technical questionnaire so comprehensively. I am sorry to hear that you have been having difficulties with this antibody. We recommend an antibody dilution of 1/200 and antigen retrieval by boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10 min followed by cooling at RT for 20 min. Your questionnaire details that you have been following a protocol in line with this. The expression data in the EXPASY database suggests that PGP9.5 is expressed in neurons and cells of the diffuse neuroendocrine system and their tumors in human cells. This area of research is outside my area of expertise. Please can you tell me whether you expect this protein to be expressed in ovine tracheal cells. Have you verified that the transcript is present it your cells? So far this antibody has only been tested using human cells and it may be that the epitope that the antibody recognizes is not present in the ovine homolog. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
