Listed are ELISA Kits for the detection of VASA, an alias name of DEAD-box helicase 4. The human protein, encoded by the gene DDX4, is 724 amino acid residues long and has a mass of 79,308 daltons. However, there are up to 4 reported isoforms. It is an enzyme of the RNA helicase class and is a member of the DEAD box helicase family, DDX4/VASA subfamily. This protein is reported to have a cytoplasmic cellular localization. For this target protein, ELISA kits with the following species reactivities are available: bovine and other mammalian. This target may also be known as: probable ATP-dependent RNA helicase DDX4, DEAD (Asp-Glu-Ala-Asp) box polypeptide 4, DEAD box protein 4, DEAD/H (Asp-Glu-Ala-Asp/His) box polypeptide 4, and DEAD (Asp-Glu-Ala-Asp) box polypeptide 4.
