The SXR ELISA kits listed below utilize specific antibodies for the plate-based assay of SXR in various samples. SXR is another term for the NR1I2 gene, which encodes the protein, nuclear receptor subfamily 1 group I member 2 in humans. It has been reported that SXR plays a role in cell differentiation and the regulation of transcription, among other functions. Structurally, the NR1I2 protein is 434 amino acid residues in length and 49.8 kilodaltons in mass. However, as many as 7 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is reported to be expressed in liver, colon and small intestine. Other names for this target antigen include BXR, ONR1, and PAR. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
