Polyunsaturated fatty acids (PUFAs) are essential nutrients that show distinct deficiency syndromes when not present in adequate amounts in the diet.[1][2] Virtually all cellular arachidonic acid is esterified in membrane phospholipids where its presence is tightly regulated through multiple interconnected pathways [3]. Free arachidonic acid is a transient, critical substrate for the biosynthesis of eicosanoid second messengers. Receptor-stimulated release, metabolism, and re-uptake of free arachidonate are all important aspects of cell signalling and inflammation.[4]
多不饱和脂肪酸(PUFAs)是必需营养素,在饮食中摄入不足时会表现出明显的缺乏综合症。几乎所有的细胞花生四烯酸都被酯化在膜磷脂中,其存在通过多个相互连接的途径进行严密调控。游离花生四烯酸是二级信使类前体,是瞬态的重要底物。受体刺激后的游离花生四烯酸的释放、代谢和重新摄取都是细胞信号传递和炎症的重要方面。

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
