These STR ELISA kits are immunodetection tools for measuring the levels of STR in biological samples. STR is an alias of the human STATH gene, which encodes the protein, statherin. The protein is reported to be a salivary protein that stabilizes saliva supersaturated with calcium salts by inhibiting the precipitation of calcium phosphate salts. The STATH protein is 62 amino acid residues in length and 7.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. This protein is known to be sulfated. Other names for this target antigen include . Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
