Ready-to-use ELISA kits are available for the detection of Spna2, an alias of the protein, spectrin alpha, non-erythrocytic 1. The official gene symbol is SPTAN1. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, chicken, and other mammalian. The protein, with a mass of 284.5 kDa and length of 2472 residues, is reported to be cytoplasmic. It is a member of the Spectrin family and may be known by other names, including: EIEE5, spectrin non-erythroid alpha subunit, fodrin alpha chain, alpha-fodrin, alpha-II spectrin, and spectrin alpha chain non-erythrocytic 1, and SPTA2.
