A number of ELISA Kits are available that target vacuolar protein sorting 28, an alias of the protein, VPS28 subunit of ESCRT-I. The human protein, encoded by the gene VPS28, is a member of the VPS28 family. The protein's cellular localization is indicated to be membrane-associated. Homology is conserved in other species, such as Mouse, Rat, Fly, Yeast, Zebrafish, Frog.
