简介：AbstractObjective:Amino acyl modification of lysine residues is an essential mechanism of nutrient sensing that regulates various biological functions including reproduction. At present, the lack of pan-specific antibodies for a recently identified lysine valylation hinders the characterization and detection of this modification. The objective of this study is to raise pan-specific antibodies that may facilitate the identification of novel expression patterns of lysine valylation.Methods:Chicken ovalbumin was valylated as an immunogen to raise polyclonal antibodies (PcAbs) in rabbits. The population of the pan-specific antibodies recognizing valylated lysine was purified using the chemically synthesized valylated peptides consisting of random amino acids. The specificity of the antibodies was evaluated using ELISA, dot blots, Western blots, and immunohistochemistry (IHC) staining in human epididymis as well.Results:A preliminary and simple strategy to make an anti-valylated lysine PcAb was developed. The recognition of the antibodies to valyllysine was evaluated as pan specific. This was useful for the detection of the newly identified valyl modification using ELISA, dot blots, and Western blots. The antibodies were also successfully utilized in IHC assays, which revealed novel valyllysine modification patterns in epididymis tissues of human.Conclusions:A new antibody tool was provided for the study of lysine valylation. The novel expression patterns of valyllysine in the epididymis suggest that this modification may be involved in sperm maturation.

简介：聚丙烯腈(PAN)是一种极为重要的化纤原料,是合成纤维的主要品种之一。据初步统计1990年国内市场消耗量40多万吨,其产量占纤维总产量的25％左右。且随着石油化学工业的发展,PAN产量在大幅度增加。然而,无论是在PAN的合成中,还是在腈纶的纺织过程中,PAN的部分丝由于分子量(小于10,000)、柔软性、卷曲度、拉伸性、弹性、勾结性等不合格,均产生一定比例的次品和“废料”。据统计,我国PAN“废料”约占PAN生产

简介：多孔的碳膜是有利地通过polyacrylonitrile(平底锅)的热分解制作了先锋，它与没有模板的technique-thermally导致的阶段分离被准备。这些碳膜拥有层次毛孔，包括越过在矩阵以及在毛孔墙上的整个膜和小毛孔的细胞的macropores。氮吸附显示micropores(1.47和1.84nm)和mesopores(2.21nm)在碳膜内存在，导致他们象1062m2/g一样大的特定的表面区域。碳膜被用来基于他们层次毛孔结构和大特定的表面区域的优点从水的答案吸附器官的染料(甲基橘子，刚果红，和玫瑰精B)。膜向甲基橘子介绍选择吸附，是特别地引人注目的，其分子的尺寸(1.2nm)是比刚果红(2.3nm)和玫瑰精B(1.8nm)的那些小的。这吸引人的结果能被归因于在分子的尺寸和毛孔之间匹配尺寸，而非静电的吸引力的位的结构。而且，使用的碳膜能容易被改革由盐酸酸，和他们的恢复吸附比率上面甚至在第三个周期维持90%。这个工作可以经由一条没有模板的途径为基于碳的吸附物向一条新线路提供层次毛孔，它能有希望地被使用有选择地在水的自河移开染料沾染物。
