| Antigen Description : |
Ubiquitin carboxyl-terminal hydrolase 7, also known as Ubiquitin thioesterase 7, Herpesvirus-associated ubiquitin-specific protease, Ubiquitin-specific-processing protease 7, USP7 and HAUSP, is a widely expressed protein which belongs to the peptidase C19 family. USP7 is a member of the family of deubiquitinating enzymes. It is involved in the regulation of stress response pathways, epigenetic silencing and the progress of infections by DNA viruses. USP7 is a protein with a cysteine peptidase core, N- and C-terminal domains required for protein-protein interactions. USP7 contributes to epigenetic silencing of homeotic genes by Polycomb (Pc). USP7 cleaves ubiquitin fusion protein substrates. It deubiquitinates TP53/p53 and MDM2 and strongly stabilizes TP53 even in the presence of excess MDM2. USP7 also induces TP53-dependent cell growth repression and apoptosis. USP7 has key roles in the p53 pathway whereby it stabilizes both p53 and MDM2. Herpes simplex virus type 1 (HSV-1) regulatory protein ICP0 stimulates lytic infection and the reactivation of quiescent viral genomes. ICP0 interacts very strongly with USP7. USP7-mediated stabilization of ICP0 is dominant over ICP0-induced degradation of USP7 during productive HSV-1 infection. The biological significance of the ICP0-USP7 interaction may be most pronounced in natural infection situations, in which limited amounts of ICP0 are expressed. |

| Species : |
Human |
| Clone : |
8C10I3 |
| Applications : |
Western blot; ELISA |
| Dilution : |
Western blot: This antibody can be used at 1-2 μg/mL with the appropriate secondary reagents to detect Human USP7 (208-560) in WB. Using a DAB detection system, the detection limit for Human USP7 (208-560) is approximately 100 ng/lane under non-reducing conditions and 4 ng/lane under reducing conditions.Direct ELISA: This antibody can be used at 0.5-1 μg with the appropriate secondary reagents to detect Human USP7 (208-560). The detection limit for Human USP7 (208-560) is approximately 0.078 ng/well. |
| Preparation : |
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, human cell-derived, recombinant Human USP7 / HAUSP. The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography. |
| Format : |
0.2 μm filtered solution in PBS with 5% trehalose |
| Storage : |
This antibody can be stored at 2-8°C for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20 to -70 °C. Preservative-Free.Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles. |
