Anti-RNase 7 antibodies enable researchers to detect and measure the RNase 7 antigen in biological samples. This target is a reported synonym of the RNASE7 gene, which encodes ribonuclease A family member 7. This protein is known to function in innate immune responses, among other biological roles. The human version of RNase 7 has a canonical amino acid length of 156 residues and a protein mass of 17.4 kilodaltons. It is reported to be a secreted protein that is notably expressed in the vagina, tonsil, and skin. RNase 7 is a member of the Pancreatic ribonuclease protein family.
