The cystinosin ELISA kits listed below utilize specific antibodies for the plate-based assay of cystinosin in various samples. cystinosin is another term for the CTNS gene, which encodes the protein, cystinosin, lysosomal cystine transporter in humans. It has been reported that cystinosin plays a role in brain development and eye development, among other functions. Structurally, the CTNS protein is 367 amino acid residues in length and 41.7 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the lysosomes and cell membrane of the cell. In terms of tissue specificity, it is reported to be highly expressed in pancreas, kidney (adult and fetal), skeletal muscle, melanocytes and keratinocytes. This protein is known to be glycosylated. Other names for this target antigen include CTNS-LSB, PQLC4, and SLC66A4.
There are cystinosin ELISA kits that can detect a target at concentrations as low as 0.156 ng/mL and as high as 10 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
