The DEAD (Asp-Glu-Ala-Asp) box polypeptide 4 ELISA kits listed below are analytical tools for measuring concentrations of DEAD (Asp-Glu-Ala-Asp) box polypeptide 4 in various samples. DEAD (Asp-Glu-Ala-Asp) box polypeptide 4 is an alternative name for the human DDX4 gene, which encodes the protein, DEAD-box helicase 4. It has been mentioned that DEAD (Asp-Glu-Ala-Asp) box polypeptide 4 plays a role in cell differentiation and spermatogenesis, among other functions. Structurally, the DDX4 protein is 724 amino acid residues in length and 79.3 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the cytoplasm of the cell. In terms of tissue specificity, it is found to be preferentially expressed in ovary and testis. Other names for this target antigen include VASA, VASA, and probable ATP-dependent RNA helicase DDX4.
