These EIF5A1 ELISA kits are immunodetection tools for measuring the levels of EIF5A1 in biological samples. EIF5A1 is an alias of the human EIF5A gene, which encodes the protein, eukaryotic translation initiation factor 5A. Notably, EIF5A1 is known to play a role in viral immune response and the regulation of transcription, among other functions. The EIF5A protein is 154 amino acid residues in length and 16.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane, nucleus, ER, and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in umbilical vein endothelial cells and several cancer cell lines. This protein is known to be acetylated. Other names for this target antigen include FABAS. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
