RUBELLA VIRUS IGG AVIDITY ELISA

Rubella Virus IgG Avidity immunoassay for the determination of Rubella-specific IgG avidity in human serum or plasma to differentiate between acute and past infection.

PRODUCT DETAILS – RUBELLA VIRUS IGG AVIDITY ELISA

  • Rubella Virus IgG Avidity assay to differentiate between acute and past infection.
  • Diagnostic performance was performed in comparison to well defined samples. The resulting relative agreement was 98.6%.

BACKGROUND

The presence of IgG antibodies to Rubella Virus indicates the occurrence of the infection but does not distinguish between recent and past infection. Virus-specific IgM antibodies are first detected approximately in ten days and peak at about four weeks post infection. They may persist for several months after acute infections. Based on the evidence that antibody avidity gradually increases after exposure to an immunogen, avidity of IgG antibodies can be used as a marker for distinguishing recent primary from long-term infections. Avidity describes the binding strength of a specific antibody to its antigen. Low-avidity IgG antibodies indicate a primary infection, whereas the presence of IgG antibodies with high avidity points to persistency or reactivation of infection.

The qualitative immunoenzymatic determination of specific antibodies is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique. Microplates are coated with specific antigens to bind corresponding antibodies of the sample (dual pipetting). After washing the wells to remove all unbound sample material, one well is incubated with avidity reagent and the corresponding well with washing buffer. The avidity reagent removes the low-avidity antibodies from the antigens whereas the high-avidity ones are still bound to the specific antigens. After second washing step to remove the rest of avidity reagent and low-avidity antibodies, a horseradish peroxidase (HRP) labelled conjugate is added. This conjugate binds to the captured antibodies. In a third washing step unbound conjugate is removed. The immune complex formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue reaction product. The intensity of this product is proportional to the amount of specific antibodies in the sample. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint colour. Absorbance at 450/620 nm is read using an ELISA microwell plate reader.

商品咨询
想了解下NpleximmunoAmp荧光标记抗体是基于什么技术?比传统的技术有什么优点和缺点?价格如何?谢谢!
请高手赐教:
我想用量子点标记抗体,但是我们实验室没有人做过,所以没总体概念,看了说明书,但是感觉不太直观,
这个试剂盒好不好用呢?标记效率怎样?有没有用过改试剂盒的人希望能帮助我。
在进行多因子检测时,因不能找到多种合适的标记一抗,而不得不选用标记二抗,因此很难避免可能发生的交叉反应及繁琐的洗涤步骤。

*不同的标记物,操作步骤略有不同。(操作步骤供参考,以英文原版说明书为准。)
标记结合物的保存:
对于任何新结合物,推荐保持于4°C条件下。如需长期保存,可添加保护剂。
缓冲液及添加剂兼容性:
A.与无胺基缓冲液兼容,包括MES,MOPS,HEPES(浓度10-50mM,pH范围6.5-8.5),LL-Modifier修饰剂提供结合反应的最佳条件。
B.常见的盐(如氯化钠)、螯合剂(EDTA)、糖对偶联反应无影响。
C.叠氮钠(0.02%-0.1%)对结合反应有轻微影响,叠氮钠不可用于HRP标记,其为后者的抑制剂。
D.甘油(upto50%)对结合效率无影响。
E.若无胺基的缓冲液浓度相对较高,pH值在6.6-8.5范围外,则需要加入更多的LL-midifier修饰剂(/10ul抗体),以此来调整pH值。最佳的pH范围为7.3-7.6左右。
F.避免使用含亲核剂的缓冲液,避免还原剂如DTT和2-巯基乙醇,乙醇胺等。
G.浓度达到或稍低于20mM的Tris对结合效率有轻微的影响。

罗氏公司的地高辛试剂盒NBT/BCIP
有谁能推荐一个价钱合理效果还行的HRP抗原标记试剂盒啊?
Annexin V-FITC/PI细胞凋亡检测试剂盒(Annexin V-FITC/PI Apoptosis Detection Kit)是用FITC标记了的Annexin V作为探针,来检测细胞早期凋亡的发生,可用荧光显微镜、流式细胞仪或其他荧光检测设备进行检测。
其检测原理为:在正常的活细胞中,磷脂酰丝氨酸(phosphotidylserine,PS)位于细胞膜的内侧,但在早期凋亡的细胞中,PS 从细胞膜的内侧翻转到细胞膜的表面,暴露在细胞外环境中。Annexin-Ⅴ(膜联蛋白-V)是一种分子量为35-36KD的Ca2+ 依赖性磷脂结合蛋白,能与PS高亲和力结合。可通过细胞外侧暴露的磷脂酰丝氨酸与凋亡早期细胞的胞膜结合。
操作步骤:
1.从室温平衡20min后的铝箔袋中取出所需板条,剩余板条用自封袋密封放回4℃。
2.设置标准品孔和样本孔,标准品孔各加不同浓度的标准品50μL;
3.样本孔中加入待测样本50μL;空白孔不加。
4.除空白孔外,标准品孔和样本孔中每孔加入辣根过氧化物酶(HRP)标记的检测抗体100μL,用封板膜封住反应孔,37℃水浴锅或恒温箱温育60min。
5.弃去液体,吸水纸上拍干,每孔加满洗涤液(350μL),静置1min,甩去洗涤液,吸水纸上拍干,如此重复洗板5次(也可用洗板机洗板)。
6.每孔加入底物A、B各50μL,37℃避光孵育15min。
7.每孔加入终止液50μL,15min内,在450nm波长处测定各孔的OD值。
求推荐一个可以直接标记糖肽的标记试剂盒,要求此试剂盒可以同时提供多糖的定性和定量信息以及多糖粘附的位点和位点占有信息。并且希望操作简单,时间短,尤其适合大批量的样品检测,并且大批量检测出的结果跟2AB基本一致。
pierce chip 试剂盒 赛默飞的啊,是美国的
用来对蛋白定量以及定位情况的研究
不同,二抗要与一抗结合,一抗与样品结合,结构当然不同。
比较急,自己买等不起。可以购买,也可以用实验室其他资源交换。

不知道发在这里合适不,实在是求助无门啊!版主手下留情。
