Anti-RNase K antibodies enable researchers to detect and measure the RNase K antigen in biological samples. This target is a reported synonym of the RNASEK gene, which encodes ribonuclease K. The human version of RNase K has a canonical amino acid length of 137 residues and a protein mass of 15.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles of cells. Other names for this target antigen include ribonuclease kappa, RNase kappa, and V-ATPase subunit f. Indicated applications for RNase K antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
