Scientific Data Images for Human Jagged 1 Antibody

Detection of Human Jagged 1 antibody by Western Blot.

Detection of Human Jagged 1 by Western Blot.

Western blot shows lysates of Huh-7 human hepatoma cell line and HepG2 human hepatocellular carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human Jagged 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1277) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Jagged 1 at approximately 180 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Jagged 1 antibody in Human Kidney Cancer Tissue by Immunohistochemistry (IHC-P).

Jagged 1 in Human Kidney Cancer Tissue.

Jagged 1 was detected in immersion fixed paraffin-embedded sections of human kidney cancer tissue using Goat Anti-Human Jagged 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1277) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Alkaline Phosphatase Production Induced by Jagged 1 and Neutralization by Human Jagged 1 Antibody.

Alkaline Phosphatase Production Induced by Jagged 1 and Neutralization by Human Jagged 1 Antibody.

Recombinant Human Jagged 1 Fc Chimera (Catalog # 1277-JG) induces alkaline phosphatase production in the C3H10T1/2 mouse embryonic fibroblast cell line in the presence of Recombinant Human/Mouse/Rat BMP-2 (Catalog # 355-BM) in a dose-dependent manner (orange line). Alkaline phosphatase production elicited by Recombinant Human Jagged 1 Fc Chimera (5 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human Jagged 1 Antibody (Catalog # AF1277). The ND50 is typically 1-5 µg/mL.

Applications for Human Jagged 1 Antibody

Application
Recommended Usage

Immunohistochemistry

5-15 µg/mL
Sample: Immersion fixed paraffin-embedded sections of human kidney cancer tissue

Western Blot

1 µg/mL
Sample: Huh‑7 human hepatoma cell line and HepG2 human hepatocellular carcinoma cell line

Neutralization

Measured by its ability to neutralize Jagged 1-induced alkaline phosphatase production in the C3H10T1/2 mouse embryonic fibroblast cell line. The Neutralization Dose (ND50) is typically 1-5 µg/mL in the presence of 5 µg/mL Recombinant Human Jagged 1 Fc Chimera.

Background: Jagged 1

Jagged 1 is a 180 kDa type I transmembrane glycoprotein and member of the Delta-Serrate-Lag-2 (DSL) family of ligands that activate LIN12/Notch proteins. Human Jagged 1 is synthesized as a 1218 amino acid (aa) precursor that contains a 33 aa signal sequence, a 1034 aa extracellular domain (ECD), a 26 aa transmembrane segment, and a 125 aa cytoplasmic region. The ECD contains a DSL domain (aa 185‑229), a cysteine-rich region, 15 EGF-like repeats, of which many bind calcium, and nine potential sites for N-linked glycosylation. Mature human Jagged 1 is 97% and 96% aa identical to mature mouse and rat Jagged 1, respectively. Jagged 1 is widely expressed in adult and fetal tissues. Jagged-Notch signaling specifies cell fate, regulates pattern formation, defines boundaries between different cell types, and modulates cell proliferation and differentiation, especially during hematopoiesis, myogenesis, neurogenesis, and development of vasculature (1‑8). Mutations in human Jagged 1 are the cause of Alagille syndrome, an autosomal-dominant disorder characterized by intrahepatic cholestasis and abnormalities of heart, eye, vertebrae, as well as characteristic facial appearance (9, 10).
