IFN-γElispot试剂盒

IFN-γElispot 是一种用于检测单个细胞分泌 人干扰素γ(IFN-γ)的细胞因子实验方法。该方法通过酶联免疫斑点实验(ELISpot)技术,实现对单个细胞分泌IFN-γ的定量检测。

HIFN-γ-ELISpot的基本原理

ELISpot是一种体外检测技术,通过将细胞置于包被有特异性抗体的96孔板中培养。在有刺激的条件下,细胞分泌的IFN-γ会被包被抗体捕获。移除细胞后,被捕获的IFN-γ用生物素标记的二抗标识,再与酶标记的亲和素作用,并加入底物使其呈色,有反应的细胞会留下直径大小不等的染色斑点‌1。

HIFN-γ-ELISpot的应用场景

HIFN-γ-ELISpot广泛应用于癌症研究、疾病探索以及疫苗研发等领域。例如,在疫苗研究中,HIFN-γ-ELISpot用于评估疫苗引起的细胞免疫效应。通过刺激疫苗接种前后的PBMCs,检测IFN-γ的分泌情况,从而评估疫苗的免疫效果‌2。此外,该方法还用于评估其他疫苗如重组蛋白疫苗、灭活疫苗和DNA疫苗引起的细胞免疫效应‌2。

HIFN-γ-ELISpot的优势

  1. ‌高灵敏度‌:能够检测到数量稀少的细胞因子分泌细胞,即使在数百万个细胞中也能准确计数‌3。
  2. ‌广泛应用‌:适用于多种研究领域,包括癌症、疾病和疫苗研发等‌23。
  3. ‌标准化操作‌:预涂板减少了测定时间并使可变性最小化,操作简便‌3。
