The SPBP ELISA kits listed below are analytical tools for measuring concentrations of SPBP in various samples. SPBP is an alternative name for the human TCF20 gene, which encodes the protein, transcription factor 20. It has been mentioned that SPBP plays a role in the regulation of transcription, among other functions. Structurally, the TCF20 protein is 1960 amino acid residues in length and 211.8 kilodaltons in mass. However, as many as 2 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 most tissues, except in ovary and prostate. Other names for this target antigen include AR1, AR1, and DDVIBA. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
