Extra Details:: Lysyl-tRNA synthetase is a homodimer localized to the cytoplasm which belongs to the class II family of tRNA synthetases. The 625aa mitochondrial enzyme and the 597aa cytoplasmic enzyme are identical over the last 576aa, but the mitochondrial enzyme has a different 49aa N-terminal containing a mitochondrial targeting sequence. Transfection of both fluorescence- tagged isoforms into an osteosarcoma cell line showed that the cytoplasmic isoform produced a diffuse, cellwide fluorescence, while the mitochondrial isoform resulted in a punctate pattern that colocalized with mitochondrial markers. Ribonuclease protection analysis indicated that the mRNA encoding the cytoplasmic isoform makes up approximately 70%, and the mitochondrial isoform approximately 30%, of mature KARS transcripts. Applications: Suitable for use in ELISA, Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:100-5000 Western Blot: 1:50-400 Immunohistochemistry (frozen): 1:50-500 Immunohistochemistry (paraffin): 1:10-100 Immunocytochemistry: 1:50-500 Optimal dilutions to be determined by the researcher.
