The eif2alpha ELISA kits listed below are analytical tools for measuring concentrations of eif2alpha in various samples. eif2alpha is an alternative name for the human EIF2S1 gene, which encodes the protein, eukaryotic translation initiation factor 2 subunit alpha. It has been mentioned that eif2alpha plays a role in pathways of aging and the response to oxidative stress, among other functions. Structurally, the EIF2S1 protein is described to be 315 amino acid residues in length and 36.1 kilodaltons in mass. It is localized to the cytoplasm of the cell. This protein is known to be phosphorylated. Other names for this target antigen include EIF-2, EIF-2A, and EIF-2alpha.
