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.\u003c\/p\u003e\n\n\u003cp\u003eConcentration: 1mg\/mL\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Recombinant fusion protein of human QARS (NP_005042.1).\u003c\/p\u003e\n\n\u003cp\u003eBuffer: PBS with 0.02% sodium azide, 50% glycerol, pH7.3.\u003c\/p\u003e\n\n\u003cp\u003ePurification Method: Affinity purification\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB \t1:500-1:2000   IHC \t1:50-1:200   IF \t1:50-1:100\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 86kDa\/87kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved MW: 88kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage: -20°C\/One year.
