Anti-cystinosis, nephropathic antibodies enable researchers to detect and measure the cystinosis, nephropathic antigen in biological samples. This target is a reported synonym of the CTNS gene, which encodes cystinosin, lysosomal cystine transporter. This protein is known to function in brain development and eye development, among other biological roles. The human version of cystinosis, nephropathic has a canonical amino acid length of 367 residues and a protein mass of 41.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the lysosomes and cell membrane of cells. Other names for this target antigen include CTNS-LSB, PQLC4, and SLC66A4. Western Blot is the most common application for the cystinosis, nephropathic antibodies listed below. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
