Anti-fru antibodies are used in antigen-specific immunodetection in biological samples. The target fru is a known alias name of the protein zinc finger and BTB domain containing 22, encoded by the ZBTB22 gene in humans. This 634-amino acid residue protein is suspected to be involved in transcriptional regulation. It is localized to the nucleus of the cell. Other synonyms for fru include BING1, ZBTB22A, and ZNF297. Western Blot is a widely used application for the fru antibodies listed below. In addition, ELISA is also a common application.
