产品详情

产品描述：

人补体成分C8β链(C8B)酶联免疫试剂盒（CSB-EL004195HU）为双抗夹心法ELISA试剂盒，定量检测血清、血浆、组织匀浆样本中的C8B含量。人补体成分C8β链（C8B）是补体系统的一部分，参与免疫反应和炎症过程。其研究机制涉及C8β链与C5b67结合，激活C8αγ，进而参与膜攻击复合物的形成，对病原体进行杀伤。试剂盒检测范围为2.74 pg/mL-2000 pg/mL，其标准化操作流程支持科研人员探究补体系统在感染、炎症或自身免疫性疾病中的作用机制，例如通过分析不同病理条件下血清或组织中C8β链的表达差异，揭示补体激活途径的调控规律。此外，还可用于评估药物干预或基因编辑模型对补体相关通路的影响，为免疫学基础研究及转化医学提供可靠工具。本品仅用于科研，不用于临床诊断，产品具体参数及操作步骤详见产品说明书。

精密度：

Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.

线性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human C8B in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:10000	Average %	92
	Range %	89-98
1:20000	Average %	90
	Range %	84-100
1:40000	Average %	95
	Range %	92-101
1:80000	Average %	93
	Range %	86-98

回收率：

The recovery of human C8B spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	96	85-104
EDTA plasma (n=4)	91	88-97

标准曲线：

These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

功能：

Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells.
基因功能参考文献：
1. The binding specificity between C8 beta and C8 alpha subunits is determined by a cooperative interaction of the N-terminal thrombospondin type 1 module and the membrane attack complex/perforin domain. PMID: 12220191
2. results indicate that the principal binding site for C9 lies within the MACPF domain of C8alpha; they also suggest this site and the binding sites for C8beta and C8gamma are distinct PMID: 16618117
