【项目简介】
LIFR (leukemia inhibitory factor receptor) belongs to the family of cytokine receptors. LIFR forms a high-affinity receptor complex with gp130, which mediates the activity of LIF (leukemia inhibitory factor) and thus affects the differentiation, proliferation, and survival of a wide variety of cells in the adult and the embryo. Besides LIF, LIFR can also bind to and activate CNTF (ciliary neurotrophic factor) and CLC (cardiotrophin like cytokine). Evidence showed that in the retina, LIFR activating LIF, CT-1 and cardiotrophin like cytokine (CLC) are strongly upregulated in response to preconditioning with bright cyclic light leading to robust activation of signal transducer and activator of transcription-3 (STAT3) in a time-dependent manner. Further, blocking LIFR activation during preconditioning using a LIFR antagonist (LIF05) attenuated the induced STAT3 activation and also resulted in reduced preconditioning-induced protection of the retinal photoreceptors. These data demonstrate that LIFR and its ligands play an essential role in endogenous neuroprotective mechanisms triggered by preconditioning-induced stress. LIFR was newly found to be a suppressor of hepatocellular carcinoma (HCC), one of the world's top five causes of cancer-related deaths.
 
【检验原理】
本试剂盒采用双抗体夹心ELISA法。酶标微孔板上预包被有抗大鼠LIFR抗体,当加入标准品和待测样本时,标准品和待测样本中的大鼠LIFR会和该抗体结合。洗板后,游离的其他成分被洗去,加入辣根过氧化物酶标记的的抗大鼠LIFR抗体可与被酶标板捕获的大鼠LIFR结合,形成“包被抗大鼠LIFR抗体+大鼠LIFR+抗大鼠LIFR抗体-HRP”免疫复合物。当加入TMB显色底物后,复合物上连接的HRP催化底物反应,生成蓝色产物,终止反应后变为黄色。在450nm处测定OD值,大鼠LIFR浓度与OD450值之间呈正比,可通过绘制标准曲线求出标本中大鼠LIFR的浓度。
