产品描述说明：Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. In metazoans, 9 aminoacyl-tRNA synthetases specific for glutamine (gln), glutamic acid (glu), and 7 other amino acids are associated within a multienzyme complex. Although present in eukaryotes, glutaminyl-tRNA synthetase (QARS) is absent from many prokaryotes, mitochondria, and chloroplasts, in which Gln-tRNA(Gln) is formed by transamidation of the misacylated Glu-tRNA(Gln). Glutaminyl-tRNA synthetase belongs to the class-I aminoacyl-tRNA synthetase family. Alternative splicing results in multiple transcript variants [taken from NCBI Entrez Gene (Gene ID: 5859)]. 品牌简介： 世界排名前十的抗体生产商，以优质的兔多克隆抗体闻名，所有抗体都经过一系列实验技术的检验，如：ELISA，WB，IP，ChIP，PLA（邻近连接技术），IHC和ICC等；不断生产出新的抗体，产品不仅针对新兴领域的热门蛋白，也包括一直以来缺少高质量检测抗体的经典蛋白。目前已拥有针对2300种目标蛋白而生产出来的近7000种一抗，同时也可提供针对来自27个种属的免疫球蛋白的二抗；抗体定制方面有40年的经验。
