These CD278 ELISA kits are immunodetection tools for measuring the levels of CD278 in biological samples. CD278 is an alias of the human ICOS gene, which encodes the protein, inducible T cell costimulator. Notably, CD278 is known to play a role in cell adhesion and immune response pathways, among other functions. The ICOS protein is 199 amino acid residues in length and 22.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. Its subcellular localization is in the cell membrane and is secreted. This protein is known to be N-glycosylated. Other names for this target antigen include AILIM and CVID1. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
