Application

溴酚蓝可用作DNA、RNA（琼脂糖）和蛋白（聚丙烯酰胺）凝胶电泳中的示踪染料。它被用于为蛋白质印迹分析制备蛋白质样品。溴酚蓝在琼脂糖凝胶中以与300-500 bp DNA大致相同的速率迁移，在蛋白聚丙烯酰胺凝胶中位于缓冲前沿。还用作血脑屏障的重要检测染料。

General description

溴酚蓝在酸性水溶液中以磺化羟基醌的形式存在。又名四溴酚磺酞。溴酚蓝是一种pH指示剂，并且是一种强蓝色染料。它带有轻微的负电荷并且与DNA同向迁移，方便用户对分子在凝胶中的移动进程进行监测。不同的凝胶组成具有不同的迁移速率。

Novel prognostic markers revealed by a proteomic approach separating benign from malignant insulinomas.

Ibrahim Alkatout et al.

Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc, 28(1), 69-79 (2014-06-21)

The prognosis of pancreatic neuroendocrine tumors is related to size, histology and proliferation rate. However, this stratification needs to be refined further. We conducted a proteome study on insulinomas, a well-defined pancreatic neuroendocrine tumor entity, in order to identify proteins

Apoptotic pore formation is associated with in-plane insertion of Bak or Bax central helices into the mitochondrial outer membrane.

Dana Westphal et al.

Proceedings of the National Academy of Sciences of the United States of America, 111(39), E4076-E4085 (2014-09-18)

The pivotal step on the mitochondrial pathway to apoptosis is permeabilization of the mitochondrial outer membrane (MOM) by oligomers of the B-cell lymphoma-2 (Bcl-2) family members Bak or Bax. However, how they disrupt MOM integrity is unknown. A longstanding model

SWI/SNF complexes are required for full activation of the DNA-damage response.

Stephanie L Smith-Roe et al.

Oncotarget, 6(2), 732-745 (2014-12-30)

SWI/SNF complexes utilize BRG1 (also known as SMARCA4) or BRM (also known as SMARCA2) as alternative catalytic subunits with ATPase activity to remodel chromatin. These chromatin-remodeling complexes are required for mammalian development and are mutated in ~20% of all human

Structural and biochemical impact of C8-aryl-guanine adducts within the NarI recognition DNA sequence: influence of aryl ring size on targeted and semi-targeted mutagenicity.

Michael Sproviero et al.

Nucleic acids research, 42(21), 13405-13421 (2014-11-02)

Chemical mutagens with an aromatic ring system may be enzymatically transformed to afford aryl radical species that preferentially react at the C8-site of 2'-deoxyguanosine (dG). The resulting carbon-linked C8-aryl-dG adduct possesses altered biophysical and genetic coding properties compared to the

Metformin attenuates hyperoxia-induced lung injury in neonatal rats by reducing the inflammatory response.

Xueyu Chen et al.

American journal of physiology. Lung cellular and molecular physiology, 309(3), L262-L270 (2015-06-07)

Because therapeutic options are lacking for bronchopulmonary dysplasia (BPD), there is an urgent medical need to discover novel targets/drugs to treat this neonatal chronic lung disease. Metformin, a drug commonly used to lower blood glucose in type 2 diabetes patients
