产品详情	4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) 是一种 4-硝基苯基 (pNP) 糖吡喃糖苷的人工底物，用于检测 α-半乳糖苷酶活性。当 4-Nitrophenyl α-D-galactopyranoside 用作底物时，释放的 pNP 量会显着增加。
生物活性	4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) is an artificial substrate of 4-nitrophenyl (pNP) glycopyranoside for detecting α-galactosidase activity. The amount of released pNP is significantly increased when 4-Nitrophenyl α-D-galactopyranoside is used as substrates.
性状	Solid
体外研究(In Vitro)	Using 4-nitorophenol (pNP)-glycopyranosides as pseudosubstrates, the amount of liberated pNP from the 4-Nitrophenyl α-D-galactopyranoside is significantly higher than that from the other pNP-glycopyranosides at pH 4.0 whereas no activity was detected at pH 7.0. The digestion assays using 4-nitrophenyl (pNP) glycopyranosides as artificial substrates shows that yieldin liberated galactose residues from 4-Nitrophenyl α-D-galactopyranoside mainly at pH 4.0, i.e. the pH level where yield threshold is decreased at most. has not independently confirmed the accuracy of these methods. They are for reference only.
运输条件	Room temperature in continental US; may vary elsewhere.
储存方式	Powder -20°C 3 years；4°C 2 years

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
