Anti-STO antibodies enable researchers to detect and measure the STO antigen in biological samples. This target is a reported synonym of the NSD1 gene, which encodes nuclear receptor binding SET domain protein 1. This protein is known to function in chromatin organization and the regulation of transcription, among other biological roles. The human version of STO has a canonical amino acid length of 2696 residues and a protein mass of 296.7 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. STO is a member of the Class V-like SAM-binding methyltransferase protein superfamily. Indicated applications for STO antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
