Application

甲醇（MeOH）已被用作通过HPLC估算血浆中丙二醛含量的洗脱液，该成分含量是氧化应激的指标。
甲醇可用于以下研究：
  • 骨髓单核细胞的集落形成单位-成纤维细胞测定。
  • 作为制备 曲霉菌 菌丝提取物的溶剂，用于通过反相高效液相色谱法测定胶霉毒素。
  • 免疫荧光研究。
  • 作为通过离子对反相高效液相色谱法分离分离核苷酸及其分解产物的洗脱液组分。

General description

已有报道称，在形状选择性沸石存在的条件下，甲醇通过热化学转化形成C2-C10 烃类化合物。其通过钌吸附原子在Ru-Pt催化剂体系上的氧化已被报道。

Packaging

ATP analogs substituted in the gamma-phosphorus (ATPgammaS, beta, gamma-imido-ATP, and beta,gamma-methylene-ATP) were used to probe the involvement of P2 receptors in the modulation of synaptic transmission in the hippocampus, because their extracellular catabolism was virtually not detected in CA1 slices.
