人凝血因子Ⅷ(FⅧ)ELISA试剂盒

人(Human)凝血因子Ⅷ(FⅧ)ELISA检测试剂盒使用说明书检测原理试剂盒采用双抗体一步夹心法酶联免疫吸附试验(ELISA)。往预先包被凝血因子Ⅷ(FⅧ)抗体的包被微孔中,依次加入标本、标准品、HRP标记的检测抗体,经过温育并彻底洗涤。用底物TMB显色,TMB在过氧化物酶的催化下转化成蓝色,并在酸的作用下转化成*终的黄色。颜色的深浅和样品中的凝血因子Ⅷ(FⅧ)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD 值),计算样品浓度。样品收集、处理及保存方法1.  血清:使用不含热原和内毒素的试管,操作过程中避免任何细胞刺激,收集血液后,3000转离心10分钟将血清和红细胞迅速小心地分离。2.  血浆:EDTA、柠檬酸盐或肝素抗凝。3000转离心30分钟取上清。3.  细胞上清液:3000转离心10分钟去除颗粒和聚合物。4.  组织匀浆:将组织加入适量生理盐水捣碎。3000转离心10分钟取上清。5.  保存:如果样本收集后不及时检测,请按一次用量分装,冻存于-20℃,避免反复冻融,在室温下解冻并确保样品均匀地充分解冻。自备物品1. 酶标仪(450nm)2. 高精度加样器及枪头:0.5-10uL、2-20uL、20-200uL、200-1000uL3. 37℃恒温箱操作注意事项1.  试剂盒保存在2-8℃,使用前室温平衡20分钟。从冰箱取出的浓缩洗涤液会有结晶,这属于正常现象,水浴加热使结晶完全溶解后再使用。2.  实验中不用的板条应立即放回自封袋中,密封(低温干燥)保存。3.  浓度为0的S0号标准品即可视为阴性对照或者空白;按照说明书操作时样本已经稀释5倍,*终结果乘以5才是样本实际浓度。4.  严格按照说明书中标明的时间、加液量及顺序进行温育操作。5.  所有液体组分使用前充分摇匀。

Store at -20 °C for one year. Avoid repeated freeze/thaw cycles. The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two weeks at 2-4 °C.Background:Integrins are heterodimers composed of noncovalently associated transmembrane a and b subunits. The 16 a and 8 b subunits heterodimerize to produce more than 20 different receptors. Most integrin receptors bind ligands that are components of the extracellular matrix, including Fibronectin, collagen and vitronectin. Certain integrins can also bind to soluble ligands, such as fibrinogen, or to counterreceptors on adjacent cells such as the intracellular adhesion molecules (ICAMs), leading to aggregation of cells. Ligands serve to cross-link or cluster integrins by binding to adjacent integrin receptors; both receptor clustering and ligand occupancy are necessary for the activation of integrin-mediated responses. In addition to mediating cell adhesion and cytoskeletal organization, integrins function as signaling receptors. Signals transduced by integrins play a role in many biological processes, including cell growth, differentiation, migration and apoptosis.
