脂质组学标准

CIL 为脂质组学研究提供多样化的稳定同位素标记和未标记脂肪酸/脂质库。这些标签有各种标签模式（即统一、部分）、形式（即游离酸、盐、酯）和材料等级（即研究、微生物/热原测试 - MPT）。脂肪酸涵盖饱和（例如，肉豆蔻酸、棕榈酸、硬脂酸）和不饱和（例如，棕榈油酸、亚油酸、油酸）类别。脂质包括神经酰胺和磷脂/溶血磷脂以及三酰基甘油酯和肉碱/酰基肉碱。这些同位素标记的化合物可用于生物样品中脂肪酸/脂质的通量测定和/或相对或绝对定量。

常见问题

溶解氘代脂肪酸 DHA 和 EPA 的合适溶剂是什么？ 氘代 DHA（例如 D₅ 猫号 DLM-10012) 和 EPA（例如，D₅ 目录号。DLM-9720) 已被证明是有效的 溶于甲醇或乙醇。

大量 CIL 脂肪酸/脂质带有 ¹³C 标记。 ¹³C 标记与 D 标记在 MS 测量中有何优势？与 D 标记相比，¹³C 标记可以提供改进的结果 同位素稳定性、可忽略的同位素扰乱问题、保守的色谱洗脱（相对于其未标记的标准品，以及更高的分析可靠性。
