一般描述

游离脂肪酸，也称为非酯化脂肪酸，在血浆中与白蛋白结合并循环。大多数游离脂肪酸要么来自于饮食来源，要么来自于脂肪组织。血浆游离脂肪酸在许多与肥胖相关的疾病中升高，可能导致外周组织的胰岛素抵抗。脓毒症和产生脂肪活性单体的肿瘤等情况也可能与游离脂肪酸水平升高有关。

脂肪酸代谢异常导致脂肪肝。肌细胞中游离脂肪酸的积累会引起心脏功能障碍风险。β-脂肪酸的升高与心肌缺血有关。

应用

游离脂肪酸检测试剂盒已可用于以下：
  • 通过测定消化样品中游离脂肪酸的含量来测定脂质水解。
  • 测定血浆和血清中的游离脂肪酸水平。
  • 定量肝组织中的游离脂肪酸水平。

适用性

适用于检测各种生物样品中的长链游离脂肪酸，如血清、血浆等体液、食品、生长培养基等。

原理

在该试剂盒中，游离脂肪酸（C8以及更长）的浓度由耦合酶测定法测定，其结果为比色法(570 nm)/荧光法(λex = 535/λem = 587 nm)产物，与脂肪酸含量成正比。

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Can these kits be used with serum samples from mouse?

    Yes, this kit can be used on mouse serum samples. We generally recommend that fresh serum samples be used. Frozen samples can probably be used. However, the successful use of frozen samples depends on the efficiency of freezing them and the amount of time they have been frozen. If previously frozen serum samples are used, you may want to check the performance of the kit with fresh vs. frozen samples.

  6. My question is not addressed here, how can I contact Technical Service for assistance?
