There are a number of ELISA Kits available for the measurement of Ubiquitin Conjugating Enzyme E2B, another term for the human protein, ubiquitin conjugating enzyme E2 B. Other synonyms may include: E2 protein, E2 ubiquitin-conjugating enzyme B, RAD6 homolog B, ubiquitin carrier protein B, ubiquitin-conjugating enzyme E2-17 kDa, ubiquitin-conjugating enzyme E2B (RAD6 homolog), and ubiquitin-protein ligase B. It is encoded by the UBE2B gene to yield a protein 152 amino acids in length and 17.3 kDa in size. The protein, an enzyme, is categorized into the Ubiquitin-conjugating enzyme family. Versions of Ubiquitin Conjugating Enzyme E2B are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
