These Helios ELISA kits are immunodetection tools for measuring the levels of Helios in biological samples. Helios is an alias of the human IKZF2 gene, which encodes the protein, IKAROS family zinc finger 2. Notably, Helios is known to play a role in the regulation of transcription, among other functions. The IKZF2 protein is 526 amino acid residues in length and 59.6 kilodaltons in mass. However, as many as 8 protein isoforms have been identified. It is localized to the nucleus of the cell. Other names for this target antigen include ANF1A2 and ZNF1A2. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
