一般描述

氯化钠是一种重要的营养素，有助于维持人类和动物的正常身体机能。这种化学物质在自然界中普遍存在，具有广泛的生物化学应用，如静脉输液和密度梯度。它也被用作稀释剂，以增加缓冲液或培养基中的离子强度。氯化钠是维持血浆渗透压和身体的细胞外液体积所必需的。过量NaCl会导致血压升高，这会导致心血管和肾脏疾病。无菌 NaCl是滴眼液的一种成分。传统上，使用高浓度盐可保存食物，因为大多数细菌不能在高盐条件下生长。

应用

氯化钠溶液可用作以下溶液的组分：

聚乙二醇(PEG)缓冲液，用于纯化双标记的产物
NT2 缓冲液，用于制备抗体包被的蛋白A琼脂糖(PAS)凝珠和免疫沉淀的核糖核蛋白（RNP)
冷冻用于从小鼠肾脏中分离单核的裂解缓冲液

特点和优势

地质上稳定
适合提纯、沉淀、结晶

Effect of prehospital induction of mild hypothermia on survival and neurological status among adults with cardiac arrest: a randomized clinical trial.

Francis Kim et al.

JAMA, 311(1), 45-52 (2013-11-19)

Hospital cooling improves outcome after cardiac arrest, but prehospital cooling immediately after return of spontaneous circulation may result in better outcomes. To determine whether prehospital cooling improves outcomes after resuscitation from cardiac arrest in patients with ventricular fibrillation (VF) and

Heterogeneity in the inter-tumor transcriptome of high risk prostate cancer.

Alexander W Wyatt et al.

Genome biology, 15(8), 426-426 (2014-08-27)

Genomic analyses of hundreds of prostate tumors have defined a diverse landscape of mutations and genome rearrangements, but the transcriptomic effect of this complexity is less well understood, particularly at the individual tumor level. We selected a cohort of 25

David G Guzzardi et al.

Journal of the American College of Cardiology, 66(8), 892-900 (2015-08-22)

Suspected genetic causes for extracellular matrix (ECM) dysregulation in the ascending aorta in patients with bicuspid aortic valves (BAV) have influenced strategies and thresholds for surgical resection of BAV aortopathy. Using 4-dimensional (4D) flow cardiac magnetic resonance imaging (CMR), we

Structural basis for self-assembly of a cytolytic pore lined by protein and lipid.

Koji Tanaka et al.

Nature communications, 6, 6337-6337 (2015-02-27)

Pore-forming toxins (PFT) are water-soluble proteins that possess the remarkable ability to self-assemble on the membrane of target cells, where they form pores causing cell damage. Here, we elucidate the mechanism of action of the haemolytic protein fragaceatoxin C (FraC)

Balanced mTORC1 activity in oligodendrocytes is required for accurate CNS myelination.

Frédéric Lebrun-Julien et al.

The Journal of neuroscience : the official journal of the Society for Neuroscience, 34(25), 8432-8448 (2014-06-21)

The mammalian target of rapamycin (mTOR) pathway integrates multiple signals and regulates crucial cell functions via the molecular complexes mTORC1 and mTORC2. These complexes are functionally dependent on their raptor (mTORC1) or rictor (mTORC2) subunits. mTOR has been associated with
