SIRT1抗体 Background
NAD-dependent deacetylase sirtuin-1, also known as SIR2-like protein 1, SIRT1 and SIR2L1, is a nucleus protein which belongs to thesirtuin family. SIRT1 / SIR2L1 is widely expressed and contains onedeacetylase sirtuin-type domain. Mammalian SIRT1 is an NAD-dependent deacetylase with critical roles in the maintenance of homeostasis and cell survival. Elevated levels of SIRT1 protein are evident in cancer in which SIRT1 can function as a cancer-specific survival factor. SIRT1 / SIR2L1 regulates processes such as apoptosis and muscle differentiation by deacetylating key proteins. It deacetylates 'Lys-382' of p53/TP53 and impairs its ability to induce proapoptotic program and modulate cell senescence. SIRT1 / SIR2L1 deacetylates TAF1B and thereby represses rDNA transcription by the RNA polymerase I. It is involved in HES1- and HEY2-mediated transcriptional repression. It inhibits skeletal muscle differentiation by deacetylating PCAF and MYOD1. SIRT1 / SIR2L1 may serve as a sensor of the cytosolic ratio of NAD+/NADH, which is essential in skeletal muscle cell differentiation. In case of HIV-1 infection, it interacts with and deacetylates the viral Tat protein.

Methods to Investigate the Role of SIRT1 in Endothelial Senescence
Sirtuins are a family of proteins with NAD+ -dependent deacetylase or mono-ADP-ribosyltransferase activity. SIRT1, the mammalian ortholog most closely related to Sir2 (the first gene of this family discovered in yeast), exhibits anti
在生命科学和医学基础研究中，或多或少都需要用到抗体。抗体的应用场景不同、标记物众多，且针对同一标记物市场上往往有多个抗体可供选择，那么，我们如何从成百万上千万种抗体中，挑选出我们想要的那支呢？ 在我们6月份的关于抗体的调研活动中，我们发现，大家更多的是去参考文献或专利中的材料和方法部分，这无疑很大程度上保证了抗体的有效性。其次有45%和34%的受访者会用到百度和谷歌，然而这两个搜索引擎覆盖面颇广，经常会出现抗体无关的搜索结果，而专业用于查找抗体的网站，大家却知之甚少。 因此，本次文章中
