来自人血浆的低密度脂蛋白,乙酰化 (AcLDL)

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):未标记
乙酰化:是
数量:200 µL (2.5 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
Activation of proteinase-activated receptor-2 in mesothelial cells induces pleural inflammation.
Authors:Lee YC, Knight DA, Lane KB, Cheng DS, Koay MA, Teixeira LR, Nesbitt JC, Chambers RC, Thompson PJ, Light RW
Journal:Am J Physiol Lung Cell Mol Physiol
PubMed ID:15591415
'Pleural inflammation underlies many pleural diseases, but its pathogenesis remains unclear. Proteinase-activated receptor-2 (PAR(2)) is a novel seven-transmembrane receptor with immunoregulatory roles. We hypothesized that PAR(2) is present on mesothelial cells and can induce pleural inflammation. PAR(2) was detected by immunohistochemistry in all (19 parietal and 11 visceral) human pleural ... More
N-glycans of SREC-I (scavenger receptor expressed by endothelial cells): essential role for ligand binding, trafficking and stability.

'Scavenger receptor expressed by endothelial cells (SREC-I) mediates the endocytosis of chemically modified lipoproteins such as acetylated low-density lipoprotein (Ac-LDL) and oxidized LDL and is implicated in atherogenesis. We produced recombinant SREC-I in Chinese hamster ovary-K1 cells and identified three potential glycosylation sites, Asn(289), Asn(382) and Asn(393), which were all ... More
Uptake and trafficking of liposomes to the endoplasmic reticulum.

'Liposomes are vesicular structures consisting of an aqueous core surrounded by a lipid bilayer. Apart from the cytosol and lysosomes, no other intracellular compartment has been successfully targeted using liposomal delivery. Here, we report the development of liposomes capable of specific targeting to the endoplasmic reticulum (ER) and associated membranes. ... More

'Scavenger-receptor class A has been held responsible for the clearance of modified LDL from the blood circulation. However, in mice deficient in scavenger-receptor class A, the decay in vivo of acetylated LDL (t1/2 < 2 min), as well as tissue distribution and liver uptake (at 5 min 77.4 +/- 4.6% ... More
