降钙素基因相关肽放射免疫测定中与内毒素交叉免疫的离体实验分析

摘要

用放射免疫法分析了内毒素对降钙素基因相关肽(CGRP)离体免疫测定的影响。结果表明离体实验中高浓度内毒素可干扰CGRP的放射免疫测定,C18柱可清除样本中的内毒素从而避免其对CGRP放射免疫测定的影响。

In vitro analysis of cross immunoreaction between CGRP and endotoxin in CGRP radioimmunoassay

Abstract

The data indicated that endotoxin interfered CGRP radioimmunoassay in vitro at high concentrations. The influence of endotoxin on CGRP radioimmunoassay can be avoided through C18 column purification for the endotoxin-containing samples.
