【摘 要】
：
本研究利用生物素-链酶亲和素系统,首次建立了信号放大化学发光免疫分析方法检测鸡伽马干扰素(ChIFN-γ),以磁性微珠为抗体固定载体,采用夹心免疫分析,结合流动注射技术[1],可实现超高灵敏的ChIFN-γ自动化化学发光免疫分析检测.链霉亲和素对生物素化抗体具有高的选择性,且一个链酶亲和素可与4个生物素结合[2].

糖基化是最普遍却也最为复杂的一种蛋白质翻译后修饰.聚糖在信号传导、生物识别、胚胎发育等一系列生物过程中发挥着至关重要的功能.糖基化修饰必须得到严格的调控,其改变或失调往往伴随着各种人类疾病,如糖尿病、炎症和癌症等.
本研究合成了新颖的钛酸锶半导体纳米材料,用链霉亲和素将该纳米材料进行生物功能化,通过链酶亲和素对生物素化抗体的特异性识别,构建了一个高灵敏的新型AFP电化学免疫传感器.采用一步夹心温育后,然后加入酶的底物硫堇和过氧化氢,引发增强的电化学检测.
Highly Selective Enrichment of Phosphopeptides with High-Index Facets Exposed Octahedral Tin Dioxide
Many efforts have been devoted into developing novel materials for selective capture and enrichment of low-abundant phosphopeptides prior to mass spectrometic analysis.In the present study, octahedral

以天然高分子壳聚寡糖为原料,通过在壳聚糖2位-NH2上引入部分疏水性烷基,在6位-OH上引入亲水性羟乙基,制得N-十二烷基-O,N-羟乙基壳聚糖(LGC)两亲性衍生物,分别用FTIR、1HNMR和元素分析等技术对其结构进行表征.此壳聚糖衍生物在水相中自组装形成胶束,以芘为荧光探针研究了其自聚集行为,结果表明制得的自聚体具有较小的临界胶束浓度(CMC为1.67×10-2mg/mL).

Spherical superparamagnetic iron oxide nanoparticles have been developed as T2-negative contrast agents for magnetic resonance imaging in clinical use because of their biocompatibility and ease of syn
目的：研究微波辅助提取赶黄草中槲皮素的最佳提取条件。方法：微波提取和水浴提取两种方法比较，采用紫外可见分光光度法，以芦丁作为标准对照，在510nm处测定槲皮素含量。结果：微波辅助提取赶黄草最佳提取条件为在255w、辐射20min、60％乙醇作溶剂固∶液=1∶10、粉碎度为40目、浸泡时间1h条件下产率最高。结论：采用微波辅助提取可以显著缩短提取时间、提高中药成分的提取率和提取质量，明显优于水浴提取
