These stromal antigen 1 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. stromal antigen 1 is an alias of the human STAG1 gene, which encodes the protein, STAG1 cohesin complex component. Notably, stromal antigen 1 is known to play a role in cell division, among other functions. The STAG1 protein is 1258 amino acid residues in length and 144.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. This protein is known to be phosphorylated. Other names for this target antigen include MRD47, SA1, and SCC3A. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
