Product Information
KE00877 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The human IL-1 alpha ELISA kit is to be used to detect and quantify protein levels of endogenous human IL-1 alpha. The assay recognizes human IL-1 alpha. An antibody specific for human IL-1 alpha has been pre-coated onto the microwells. The human IL-1 alpha protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for human IL-1 alpha is added to detect the captured human IL-1 alpha protein. For signal development, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Interleukin-1α (IL-1 alpha) is a protein that plays a crucial role in the regulation of a number of key cellular processes. IL-1 alpha is a cytokine and a potent mediator of body's response to inflammation, microbial invasion, tissue injury and immunological response. In addition, recent studies suggest that IL-1 alpha also has a role in wound healing, rheumatoid arthritis, Alzheimer's disease and tumor growth. IL-1 alpha functions as an alarmin during the process of sterile inflammation. It serves as a signal from dying cells to potentiate the inflammatory response, increasing the expression of other secreted factors like IL-6 and IL-8. IL-1 alpha was found to affect the cell cycle of osteosarcoma cell to reduce cell growth.

FAQ
1、我的样本稀释液有限,如何处理稀释倍数较大的样本?
我们建议您对样本进行梯度稀释。例如,人血清样本需要1000000倍稀释时,您可以分3个梯度,每个梯度100倍,进行稀释:
第一步:取2 uL人血清样本,加入198 uL样本稀释液,混匀得到100倍稀释的人血清样本
第二步:取2uL 100倍稀释的人血清样本+ 198 uL样本稀释液进行稀释,混匀得到10000倍稀释的人血清样本
第三步:取2uL 10000倍稀释的人血清样本+ 198 uL样本稀释液进行稀释,混匀得到1000000倍稀释的人血清样本。
如果样本需要进一步稀释,您可以使用更多梯度。除了我们推荐的样本稀释液,不建议您使用其他溶液或者水稀释。如果您的样本稀释液仍然不足,请联系我们的客服为您提供更多样本稀释液。

文献和实验葡萄糖来源 AGEs ELISA 检测试剂盒 ( Glucose-derived AGEs ELISA Kit ) 研 究 背 景 越来越多的证据指出晚期糖基化终端产物( AGEs )修饰蛋白严重影响到老龄化人群的健康问题。 AGEs 是葡萄糖与自由的蛋白质氨基基团发生非酶促糖基化反应的终端不可逆代谢产物的总称。其在人体内的积累会引发组织或器官一系列的病理性变化,从而导致白内障、阿尔茨海默氏病、骨关节炎、心功
正文炎症等免疫研究中 IL-1 家族的成员是重要的研究对象。这些促炎症和抗炎症因子在有机体应对病原感染和损伤时扮演了重要作用。IL-1β 有其自身鲜明的特点,实验前需要多了解。下面让我们来一一解读。1. 靶标生物学特点IL-1β 是 IL-1 家族众多成员中研究的最为深入的成员。包括免疫细胞(如单核细胞和巨噬细胞)在内的很多细胞都可以产生并分泌。IL-1β 的释放大致分为 3 个步骤:i)无活性前体的产生;ii)前体的成熟活化;iii)活化蛋白向胞外的分泌。众多刺激都会诱导这个过程,可分为病原
体外诱生的IL-1来反映体内IL-1活性水平。 【基本原理】 LPS是IL-1α与IL-1β的诱生物,能在体外诱导单核/巨噬细胞产生IL-1α与IL-1β。下面重点介绍以小鼠腹腔巨噬细胞活性制备IL-1。 【材料和试剂】 (1) BALB/c或C57BL/6小鼠:6-10周龄,雌雄均可。 (2) 75%酒精 (3) LPS:10% FCS-RPMI-1640培养液配制成10μg/ml。 (4) 5% FCS
