产品介绍
PMA 是一种高亲和性的 DNA 结合染料，该染料本身具有微弱的荧光，但与核酸结合后可以发出更为明亮的荧光。它尤其与双链 DNA 具有高亲和性。PMA 不能透过细胞膜，因此只能选择性标记死细胞上暴露在外的 DNA。这个特性使得 PMA 可以通过实时定量 PCR（qPCR）的手段，广泛用于可被培养的病原细胞的筛选，因为 PMA 可与死细胞上的 DNA 牢固结合，而不能用于 PCR 反应的扩增。PMA 的这个特性使其可以通过实时定量 PCR 的手段，广泛用于可被培养的病原细菌的筛选。
注意事项
1. 荧光染料均存在淬灭问题，请尽量注意避光，以减缓荧光淬灭。
2. 为了您的安全和健康，请穿实验服并戴一次性手套操作。
