Listed are ELISA Kits for the detection of L21mt, an alias name of mitochondrial ribosomal protein L21. The human protein, encoded by the gene MRPL21, is 205 amino acid residues long and has a mass of 22,815 daltons. However, there are up to 2 reported isoforms. It is a member of the Bacterial ribosomal protein bL21 family. This protein is reported to have a mitochondrial cellular localization. This target may also be known as: 39S ribosomal protein L21 mitochondrial, mitochondrial large ribosomal subunit protein bL21m, L21mt, and MRP-L21.
