Application

用十二水合磷酸钠制备缓冲液，用于高效液相色谱法分析人全血和血浆中的咯萘啶。

Biochem/physiol Actions

磷酸钠三碱也被称为磷酸三钠或TSP，是一种广泛使用的清洗剂。磷酸三钠破坏了肠炎沙门氏菌细胞的细胞质和外膜，因此阻止了细菌的传播。 此外，它是铁的腐蚀抑制剂，可抑制无缓冲溶液中阳极铁溶解反应的速率。

Temporal summation of pain (TSP), the perception of increasingly greater pain evoked by repetitive noxious stimuli, is highly variable between individuals. Individuals with facilitated pain processing and/or reduced pain-modulatory capabilities are regarded as pronociceptive, whereas individuals with reduced pain processing
