Tetrabromocinnamic Acid (TBCA) is a new class of specific protein kinase CK2 inhibitors [1].
Protein kinases have been involved in catalyzing the phosphorylation of serine, threonine and tyrosine residues in protein substrates that play dominant roles in controlling nearly all cellular functions. The Ser/Thr-specific protein kinase CK2 has been implicated in signal transduction, gene expression, DNA repair, RNA and protein synthesis. CK2 is invariably elevated in a wide spectrum of tumours [1].
In vitro: TBCA was a selective, cell-permeable inhibitor of CK2 with an IC50 of 0.11 μM. The Ki value was 77 nM. TBCA showed minimal effect on a panel of 28 other kinases. TBCA induced cell death in Jurkat adult T cell leukemia cells with an DC50 of 7.7 μM [1]. TBCA dose-dependently inhibited platelet aggregation and secretion induced by various agonists including 2-MeSADP, AYPGKF, SFLLRN, and CRP [2]. TBCA also significantly inhibited agonist-induced thromboxane A2 (TxA2) generation and ERK phosphorylation. TBCA significantly inhibited platelet spreading on immobilized fibrinogen surface and clot retraction mediated by integrin αIIbβ3 signaling [2].

纯水机,跟净水机或者净水器的区别是需要用电(大多数),有一个真空储水罐,纯水机包含了净水机或者净水器的功能和使用材质,过滤更高可达到万分之一微米,因为最重要的是它采用了RO反渗透技术,因为过滤更精细,所以一般的水压是不能顺畅通过的,所以需要用电,电要带动机器本身佩戴的增压泵来给原水打压才能通过。
事实上很多细菌病毒异色异味也只有纯水机能完全的过滤掉。
这只是一些最基本的常识。希望对楼主有帮助吧,本人专业从事净水行业多年,也可以看本人以往的知道回答!
纯水机的价格影响因素除了进口品牌和国产品牌的差异外,主要取决于产量、用途以及其他特殊要求。
综合来看,除非有硬性规定或者需要采用进口品牌来提升实验室形象,否则建议选择国产品牌即可,因为实际上纯水机作为实验室常规设备,在工艺技术上知名度较高的国产品牌已足与进口相媲美,且价格仅为进口的1/3左右。
你需要先确定采购水机的主要实验用途,不同的实验用途,对水的要求是不一样的,从而也决定了所采购纯水机的配置,进而决定价格。
水中需纯化的物质主要有:无机离子、总有机碳(TOC)、微小粒子、微生物(内毒素、热原)、弱电解质。根据对以上物质的去除度,生产出来的纯水分为三个级别:初级纯水、中级水、超纯水。一般来水,仅产初级产水的纯水机价格在1.2万左右(产量10L);同时产初级纯水和超纯水的纯水机价格在(2-3万左右,产量10L)。
此外,还需要确定具体的实验用途,不同的实验用水,对于水中的物质去除度是有区分的,会有一定的倾斜度,比如细胞培养型实验,就对无机离子和TOC去除度要求严格;无机分析实验的话对无机离子去除要求高。
国产中,锐思捷、力康都还不错。
有些同行用娃哈哈,能满足药典吗?纯水机呢?
五大过滤功效:去除异色、异味、重金属、杜绝细菌、根除水碱。
超滤净水机过滤精度达0.01微米,它具有更高的强度,更好的安全性能以及更大的水通量等特性。四大过滤功效:去除异色、异味、重金属、杜绝细菌
纯水机,是利用反渗透膜产出纯净水的净水机,属于直饮机。
二者区别:直饮机是一个统称,包含纯水机、超滤直饮机等;纯水机就是生产纯净水的机器,出水可以直接饮用。
