The NA1/NA2 ELISA kits listed below are analytical tools for measuring concentrations of NA1/NA2 in various samples. NA1/NA2 is an alternative name for the human CLU gene, which encodes the protein, clusterin. It has been mentioned that NA1/NA2 plays a role in innate immune responses and the apoptotic pathway, among other functions. Structurally, the CLU protein is 449 amino acid residues in length and 52.5 kilodaltons in mass. However, as many as 6 protein isoforms have been identified. Its subcellular localization is in the cytoplasmic vesicles and is secreted. In terms of tissue specificity, it is notably expressed in blood plasma, cerebrospinal fluid, milk, seminal plasma and colon mucosa. This protein is known to be N-glycosylated, ubiquitinated, cleaved and sulfated. Other names for this target antigen include AAG4, APO-J, and APOJ.
