来自人血浆的低密度脂蛋白,DiI 复合物 (DiI LDL)

人低密度脂蛋白 (LDL) 是大蛋白复合物 (∼500,000 Da),其可与脊椎动物细胞表面的特定受体结合,通过受体介导的内吞作用传递胆固醇 — 标记的 LDL 复合物是研究这一现象的有用工具。这些实验通常通过加入荧光标记的了解更多信息

人低密度脂蛋白 (LDL) 是大蛋白复合物 (∼500,000 Da),其可与脊椎动物细胞表面的特定受体结合,通过受体介导的内吞作用传递胆固醇 — 标记的 LDL 复合物是研究这一现象的有用工具。这些实验通常通过加入荧光标记的 LDL 来培养细胞,并通过显微镜或流式细胞术进行分析。或者,荧光标记的 LDL 可注入检测动物,并且可在指定的时间段后分析标记的分布。我们提供一个未标记的 LDL 和两类标记的 LDL:含有未修饰载脂蛋白的 LDL(用于研究正常胆固醇传递和内吞)和含有乙酰化 (Ac) 载脂蛋白的 LDL(用于研究特异性表达这种乙酰化 LDL 的受体的细胞类型(即内皮细胞和小胶质细胞))。

LDL 规格:

标记 (Ex/Em):Dil (554/571)
乙酰化:否
含量:200 µL (1.0 mg/mL)

持续制备新鲜的 LDL
我们大约每两个月采用新鲜人血浆制备 LDL 和 AcLDL 产品。非乙酰化 LDL 产品在其制备后两周内发货。所有的乙酰化 LDL 产品均持续供应。

非乙酰化与乙酰化 LDL
含未修饰载脂蛋白的 LDL 可用于研究正常胆固醇传递和内吞。如果 LDL 的载脂蛋白的赖氨酸残基被乙酰化,则 LDL 复合物不再与 LDL 受体结合,而是由拥有特异性针对该修饰形式的“清道夫”受体的内皮细胞和小胶质细胞摄取。

标记的 LDL 的主要应用
LDL 复合物的其中一些应用包括:
•细胞表面 LDL 受体的计数以及内吞后分析其运动和聚集
• 在成纤维细胞中定量分析 LDL 受体活性(替代放射性标记的 LDL 测定)
• 研究不同细胞系中的 LDL 表达并识别 LDL 受体缺陷

常见问题解答 (FAQ)

If the Low Density Lipoprotein (LDL) from Human Plasma was accidentally frozen, can I still use it?

We recommend storing Low Density Lipoprotein (LDL) from Human Plasma at 2-8 degrees C. We do not recommend using frozen product.

Abstract
Nobiletin attenuates VLDL overproduction, dyslipidemia, and atherosclerosis in mice with diet-induced insulin resistance.
Authors:Mulvihill EE, Assini JM, Lee JK, Allister EM, Sutherland BG, Koppes JB, Sawyez CG, Edwards JY, Telford DE, Charbonneau A, St-Pierre P, Marette A, Huff MW,
Journal:Diabetes
PubMed ID:21471511
Increased plasma concentrations of apolipoprotein B100 often present in patients with insulin resistance and confer increased risk for the development of atherosclerosis. Naturally occurring polyphenolic compounds including flavonoids have antiatherogenic properties. The aim of the current study was to evaluate the effect of the polymethoxylated flavonoid nobiletin on lipoprotein secretion ... More

'Phagocytosis is a pivotal process by which macrophages eliminate microorganisms after recognition by pathogen sensors. Here we unexpectedly found that the self ligand and cell surface receptor SLAM functioned not only as a costimulatory molecule but also as a microbial sensor that controlled the killing of gram-negative bacteria by macrophages. ... More

'The low density lipoprotein (LDL) receptor is responsible for removing the majority of the LDL cholesterol from the plasma. Mutations in the LDL receptor gene cause the disease familial hypercholesterolemia (FH).
