These E2 protein ELISA kits are immunodetection tools for measuring the levels of E2 protein in biological samples. E2 protein is an alias of the human UBE2B gene, which encodes the protein, ubiquitin conjugating enzyme E2 B. Notably, E2 protein is known to play a role in the apoptotic pathway and DNA damage pathways, among other functions. The UBE2B protein is described to be 152 amino acid residues in length and 17.3 kilodaltons in mass. It is localized to the nucleus and cell membrane of the cell. Other names for this target antigen include E2-17kDa, HHR6B, and HR6B. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
