Scientific Data Images for Human ISG15/UCRP Antibody

Detection of Human ISG15/UCRP antibody by Western Blot.

Detection of Human ISG15/UCRP by Western Blot.

Western blot shows lysates of MCF-7 human breast cancer cell line and HT-29 human colon adenocarcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human ISG15/UCRP Monoclonal Antibody (Catalog # MAB4845) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for ISG15/UCRP at approximately 15 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Detection of Human ISG15/UCRP by Simple WesternTM.

Simple Western lane view shows lysates of MCF-7 human breast cancer cell line and HT-29 human colon adenocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for ISG15/UCRP at approximately 20 kDa (as indicated) using 5 µg/mL of Mouse Anti-Human ISG15/UCRP Monoclonal Antibody (Catalog # MAB4845) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Detection of ISG15/UCRP in Human Endometrial Cancer.

ISG15/UCRP was detected in immersion fixed paraffin-embedded sections of Human Endometrial Cancer using Mouse Anti-Human ISG15/UCRP Monoclonal Antibody (Catalog # MAB4845) at 0.5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in cancer cells.

Background: ISG15/UCRP

ISG15 (interferon-induced 15 kDa protein; also known as IP17) is a 15 kDa ubiquitin family protein that is expressed by a wide variety of cell types. ISG15 is induced by type I IFN, and like ubiquitin, becomes conjugated to intracellular proteins. Unlike ubiquitin, it does not target proteins for degradation. Instead, it is part of the antivirus response. Human proISG15 is 165 amino acids (aa) in length. There are two ubiquitin-like domains (aa 2‑78 and 79‑157) and a propeptide (aa 158‑165) that is cleaved intracellularly. Select blood mononuclear cells secrete mature ISG15, which is chemotactic for neutrophils. Mature human ISG15 shares 66% aa sequence identity with mouse ISG15.
