腺病毒IgA、IgG免疫诊断试剂盒
检验原理
用抗原包被微量板孔,制成固相载体。加患者血清到板孔中,其所含的抗体特异性地与固相载体中现存抗原结合,形成免疫复合物。除去多余物质后,加入结合了碱性磷酸酶的IgG、IgA或IgM抗体,使之与上述免疫复合物反应。洗板,除去多余的结合物,加入底物(对硝基苯磷酸盐)。其与酶结合的免疫复合物反应,产生有颜色产物,颜色强度与特异性抗体含量成正比。
产品规格:96T/盒
存储条件:4-8℃

细胞
尤其是近年来,随着引物与探针的设计更精确、多通道荧光PCR仪
的开发与广泛使用,多重荧光定量PCR技术日臻成熟,并以其高通
量、低成本、高效率等优点而广泛应用于病毒、细菌、真菌等多
种病原体的快速检测,成为应用的热点.
基因芯片
与PCR方法相比,基因芯片技术能同时获得更多病原学、生物学方
面的信息,从而更为全面地分析、掌握病原微生物的特征。Vora
等[12]运用基因芯片技术对多种致病性弧菌的毒力、毒素、耐药
基因及潜在的毒力基因进行全面分析,对掌握这些细菌的致病性
及进行有效预防、控制等具有重要意义。但基因芯片成本较高,
距离推广应用尚需时间等待[2] 。
症状
人类在自然情况下是霍乱弧菌的*易感者,主要通过污染的水
源或饮食物经口传染。在一定条件下,霍乱弧菌进入小肠后,依
靠鞭毛的运动,穿过粘膜表面的粘液层,可能藉菌毛作用粘附于
肠壁上皮细胞上,在肠粘膜表面迅速繁殖,经过短暂的潜伏期后
便急骤发病。该菌不侵入肠上皮细胞和肠腺,也不侵入血流,仅
在局部繁殖和产生霍乱肠毒素,此毒素作用于粘膜上皮细胞与肠
腺使肠液过度分泌,从而患者出现上吐下泻,泻出物呈“米泔水
样”并含大量弧菌,此为本病典型的特征。
霍乱肠毒素本质是蛋白质,不耐热,56℃经30分钟,即可破坏其
活性。对蛋白酶敏感而对胰蛋白酶抵抗。该毒素属外毒素,具有
很强的抗原性。现已能将该毒素高度精制成晶状,仍保持*的
生物学活性。
霍乱肠毒素致病机理如下:毒素由A和B两个亚单位组成,A亚单位
又分为A1和A2两个肽链,两者依靠二硫链连接。A亚单位为毒性单
位,其中A1肽链具有酶活性,A2肽链与B亚单位结合参与受体介导
的内吞作用中的转位作用。B亚单位为结合单位,能特异地识别肠
上皮细胞上的受体。1个毒素分子由一个A亚单位和4℃6个B亚单位
组成多聚体。
Especially in recent years, with the design of primers and probes more accurate, multi-channel fluorescence PCR instrument
The development and widespread use of multiplex fluorescent quantitative PCR technologies are becoming more mature and their high-pass
Volume, low cost, high efficiency and other advantages and widely used in viruses, bacteria, fungi and more
The rapid detection of pathogens, become a hot spot.
Gene chip
Compared with the PCR method, gene chip technology can get more etiology, biology side
Surface information, so as to more fully analyze and master the characteristics of pathogenic microorganisms. Vora
[12] using gene chip technology for a variety of pathogenic Vibrio virulence, toxins, resistance
Genes and potential virulence genes are thoroughly analyzed to understand the pathogenicity of these bacteria
And effective prevention, control and other important. However, the high cost of gene chips,
Distance application still need time to wait [2].
symptom
Humans are the only susceptible to Vibrio cholerae in natural conditions, primarily through contaminated water
Source or food contaminated. Under certain conditions, Vibrio cholera into the small intestine, according to
By flagellar movement, mucous membrane through the mucosal surface, may be attached to the role of pili
Intestinal wall epithelial cells, the rapid proliferation of intestinal mucosal surface, after a short period of incubation
It is a sudden onset. The bacteria do not invade intestinal epithelial cells and enteric glands, nor invasion of blood flow, only
In the local reproduction and produce cholera enterotoxin, this toxin in mucosal epithelial cells and intestine
Gland to make excessive secretion of intestinal fluid, which appears on the patient diarrhea, diarrhea was "rice water
Like "and contains a large number of Vibrio, this is a typical feature of the disease.
Cholera enterotoxin is a protein in nature, not heat, 56 ℃ by 30 minutes, you can destroy it
active. Protease sensitive to trypsin resistance. The toxin is an exotoxin that has
Strong antigenicity. The toxin is now highly refined into a crystalline form and remains extremely strong
Biological activity.
The pathogenesis of cholera enterotoxin is as follows: toxin consists of two subunits A and B, A subunit
Divided into two A1 and A2 peptide chain, the two rely on disulfide link. A subunit is toxic
Of which A1 peptide chain has enzymatic activity, A2 peptide chain and B subunit binding receptor-mediated
The role of translocation in endocytosis. B subunit for the binding unit, can specifically identify the intestine
Receptors on epithelial cells. One toxin molecule consists of one A subunit and four B subunits at 4 ° C
Composition of multimers.
