We evaluated a method for quantifying botulinum toxin-neutralizing antibodies which utilizes the CMAP. This method can be used just one day after administration, and the detection sensitivity was higher than that of the mouse neutralization test. The CMAP neutralization test detected neutralizing antibodies in patients who were resistant to treatment with the botulinum LL toxin. These results indicate that the CMAP neutralization test is useful for detecting low levels of antitoxin.
我们评估了一种利用 CMAP 定量检测肉毒毒素中和抗体的方法。该方法在给药后一天即可使用,检测灵敏度高于小鼠中和试验。CMAP 中和试验检测到了对肉毒梭菌 LL 毒素治疗有抗性的患者体内的中和抗体。这些结果表明,CMAP 中和试验可用于检测低水平的抗毒素。
