The PAP procedure was compared with the peroxidase labelled antibody sandwich method and was found to be at least 20 times more sensitive. Background staining was reduced by the addition of normal swine serum to all the immune sera or by pretreating sections with it at the beginning of either method. The PAP procedure could be effectively reduced to a period of 1 hour or less.
将PAP法与过氧化物酶标记抗体夹心法进行比较,发现前者的敏感性至少高20倍。通过在所有免疫血清中加入正常猪血清,或者在任何一种方法开始时用其预处理切片,可减少背景染色。PAP法可有效地缩短至1小时或更短时间。
