| 背景 | Members of Lipocalin family share a highly conserved fold with an eight-stranded antiparallel beta barrel, and act as a transporters, carrying small molecules to specific cells. Lipocalin-2, also known as Neutrophil Gelatinase-Associated Lipocalin (NGAL), was originally identified as a component of neutrophil granules. It is a 25 kDa protein existing in monomeric and homo- and heterodimeric forms, the latter as a dimer with human neutrophil gelatinases (MMP-9). Its expression has been observed in most tissues normally exposed to microorganism, and its synthesis is induced in epithelial cells during inflammation. Lipocalin-2 has been implicated in a variety of processes including cell differentiation, tumorigenesis, and apoptosis. Studies indicate that Lipocalin-2 binds a bacterial catecholate sidropore bound to ferric ion such as enterobactin with a subnanomolar dissociation constant (Kd = 0.41 nM). The bound ferric enterobactin complex breaks down slowly in a month into dihydroxybenzoyl serine and dihydroxybenzoic acid (DHBA). It also binds to a ferric DHBA complex with much less Kd values (7.9 nM). Secretion of Lipocalin‑2 in immune cells increases by stimulation of Toll-like receptor as an acute phase response to infection. As a result, it acts as a potent bacteriostatic reagent by sequestering iron. Moreover, Lipocalin-2 can alter the invasive and metastatic behavior of Ras-transformed breast cancer cells in vitro and in vivo by reversing epithelial to mesenchymal transition inducing activity of Ras, through restoration of E-cadherin expression, via effects on the Ras-MAPK signaling pathway. |

Detection of Human Lipocalin‑2/NGAL by Western Blot. Western blot shows lysates of Capan‑1 human pancreatic adenocarcinoma cell line and human pancreas tissue. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human Lipocalin‑2/NGAL Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1757) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Lipocalin‑2/NGAL at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
Lipocalin‑2/NGAL in Human Pancreatic Cancer Tissue. Lipocalin‑2/NGAL was detected in immersion fixed paraffin-embedded sections of human pancreatic cancer tissue using Goat Anti-Human Lipocalin‑2/NGAL Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1757) 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).

Detection of Human Lipocalin‑2/NGAL by Simple WesternTM. Simple Western lane view shows lysates of Capan‑1 human pancreatic adenocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Lipocalin‑2/NGAL at approximately 34 kDa (as indicated) using 2 µg/mL of Goat Anti-Human Lipocalin‑2/NGAL Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1757) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
