Lipocalin-2 (LCN2) (also known as Neurophil Gelatinase-Associated Lipocalin or NGAL) belongs to a superfamily of lipocalins, a collection of small, diversely functional, extracellular proteins. Lipocalin-2 is secreted from neutrophil granules in three different forms: a monomer of 25 kDa, a disulfide-linked homodimer at 46 kDa, and a disulfide-linked heterodimer with MMP-9 at 135-kDa. It is widely known to induce development of kidney epithelia, to bind and traffic iron, and to act as a molecular signal under inflammatory conditions, such as Crohn’s Disease. Multiple carcinoma studies have also shown elevated expression levels of Lipocalin-2 in several different human tumors affecting such organs as colon, lung, breast, ovaries, and pancreas. Additionally, there has been great interest in this protein as a possible marker for onset of Acute Kidney Injury following cardiac surgery, the progression of Chronic Kidney Disease (CKD), and the survival chances of patients with Chronic Heart Failure (CHF).，官网链接：https://www.sigmaaldrich.cn/product/mm/mabn481 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
