Anti-SOM antibodies enable researchers to detect and measure the SOM antigen in biological samples. This target is a reported synonym of the GRHL3 gene, which encodes grainyhead like transcription factor 3. This protein is known to function in nervous system development and epidermis development, among other biological roles. The human version of SOM has a canonical amino acid length of 626 residues and a protein mass of 70.3 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. SOM is a member of the Grh/CP2 protein family. Indicated applications for SOM antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
