利用辣根过氧化物酶(HRP)追踪神经联系的方法是七十年代发展起来的一种有效方法。这种方法开始用于周围神经,1972年由Lavail等首次用于中枢神经系统。HRP法的呈色反应根据色素原,孵化参数的不同,目前已有九种呈色方法。在以后的实验研究中,学者们都希望使用敏感度高的方法来探索中枢神经的形态联系。但目前有关 The use of horseradish peroxidase (HRP) to track neural connections was an effective method developed in the seventies. This method began to be used for peripheral nerves, first used by the Central Nervous System in 1972 by Lavail et al. The color reaction of HRP method according to the pigment original, different incubation parameters, there are nine kinds of color method. In the future experimental research, scholars all hope to explore the morphological connection of central nervous system with high sensitivity. But relevant at the moment
