The GUCY1B3 ELISA kits listed below utilize specific antibodies for the plate-based assay of GUCY1B3 in various samples. GUCY1B3 is another term for the GUCY1B1 gene, which encodes the protein, guanylate cyclase 1 soluble subunit beta 1 in humans. The target protein is known to mediate responses to nitric oxide (NO) by catalyzing the biosynthesis of the signaling molecule cGMP. Structurally, the GUCY1B1 protein is 619 amino acid residues in length and 70.5 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cytoplasm of the cell. In terms of tissue specificity, it is notably expressed in the brain cortex and cerebellum. Other names for this target antigen include GC-S-beta-1, GC-SB3, and GUC1B3. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
