Image	IHC image of CSB-RA118372A0HU diluted at 1:100 and staining in paraffin-embedded human breast cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB. Immunofluorescence staining of HeLa cell with CSB-RA118372A0HU at 1:50 , counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L). Overlay Peak curve showing Hela cells stained with CSB-RA118372A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/110⁶cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/110⁶cells) used under the same conditions. Acquisition of >10, 000 events was performed.

Description

USP13 is a deubiquitinating enzyme that plays a critical role in regulating protein stability through the removal of ubiquitin chains from target substrates. As a member of the ubiquitin-specific protease family, USP13 influences diverse cellular processes including autophagy, DNA damage response, and tumor suppression pathways. Its involvement in modulating the stability of key regulatory proteins has made it an important target for researchers investigating epigenetic mechanisms and nuclear signaling networks, particularly in cancer biology contexts.

This recombinant monoclonal antibody against human USP13 offers the reproducibility and consistency that demanding experimental workflows require. Generated using recombinant technology and produced as clone 11H3 in rabbit host, this antibody provides sequence-defined specificity that eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived reagents. The defined molecular composition ensures that your results remain comparable across extended studies and collaborative projects.

Validation across multiple detection platforms demonstrates this antibody's versatility in your research applications. Immunohistochemistry studies using paraffin-embedded human breast cancer tissue at dilutions of 1:50-1:200 reveal clear target detection, making it suitable for examining USP13 expression in clinical specimens. Immunofluorescence analysis in HeLa cells confirms cytoplasmic and nuclear localization patterns, while flow cytometry validation in the same cell line provides quantitative assessment capabilities for population-level studies.

Whether you are investigating USP13's role in protein quality control mechanisms, exploring its contributions to oncogenic pathways, or characterizing its expression across tissue samples, this antibody delivers the technical performance needed for publication-quality data in epigenetics and nuclear signaling research.

Target Background

Function

Deubiquitinase that mediates deubiquitination of target proteins such as BECN1, MITF, SKP2 and USP10 and is involved in various processes such as autophagy and endoplasmic reticulum-associated degradation (ERAD). Component of a regulatory loop that controls autophagy and p53/TP53 levels: mediates deubiquitination of BECN1, a key regulator of autophagy, leading to stabilize the PIK3C3/VPS34-containing complexes. Also deubiquitinates USP10, an essential regulator of p53/TP53 stability. In turn, PIK3C3/VPS34-containing complexes regulate USP13 stability, suggesting the existence of a regulatory system by which PIK3C3/VPS34-containing complexes regulate p53/TP53 protein levels via USP10 and USP13. Recruited by nuclear UFD1 and mediates deubiquitination of SKP2, thereby regulating endoplasmic reticulum-associated degradation (ERAD). Also regulates ERAD through the deubiquitination of UBL4A a component of the BAG6/BAT3 complex. Mediates stabilization of SIAH2 independently of deubiquitinase activity: binds ubiquitinated SIAH2 and acts by impairing SIAH2 autoubiquitination. Has a weak deubiquitinase activity in vitro and preferentially cleaves 'Lys-63'-linked polyubiquitin chains. In contrast to USP5, it is not able to mediate unanchored polyubiquitin disassembly. Able to cleave ISG15 in vitro; however, additional experiments are required to confirm such data.
