产品描述:CUSABIO人绿脓杆菌外毒素A(PEA)酶联免疫检测试剂盒(货号:CSB-E11252h),基于双抗体夹心法原理实现定量分析,适用于血清、唾液及组织匀浆样本中PEA蛋白的检测。绿脓杆菌(铜绿假单胞菌)作为常见机会性致病菌,其分泌的外毒素A(PEA)通过抑制宿主细胞蛋白质合成引发组织损伤,是研究细菌致病机制及宿主免疫应答的关键靶标。本试剂盒检测灵敏度为0.156 ng/mL,线性范围覆盖0.156-10 ng/mL,可满足微量样本中PEA的动态监测需求。实验采用预包被特异性抗体的96孔板,通过生物素标记检测抗体与链霉亲和素-HRP显色系统实现高特异性结合,配合标准品建立标准曲线完成目标物定量。该产品可应用于基础科研中感染模型建立、宿主-病原体互作研究、抗生素疗效评估等场景,例如通过检测不同感染阶段生物样本中的PEA浓度变化,揭示毒素释放规律及其与疾病进展的关联性,或用于筛选抑制PEA活性的潜在化合物。实验全程无需特殊设备,常规酶标仪即可完成读数,操作流程标准化。

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 PEA 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) 1:1 Average % 85 Range % 80-92 1:2 Average % 94 Range % 87-105 1:4 Average % 97 Range % 92-102 1:8 Average % 99 Range % 91-105 -
回收率:
The recovery of human PEA 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) 87 81-96 -
