These gp340 ELISA kits are immunodetection tools for measuring the levels of gp340 in biological samples. gp340 is an alias of the human DMBT1 gene, which encodes the protein, deleted in malignant brain tumors 1. Notably, gp340 is known to play a role in viral immune response and epithelial cell differentiation, among other functions. The DMBT1 protein is 2413 amino acid residues in length and 260.7 kilodaltons in mass. However, as many as 9 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is reported to be highly expressed in alveolar and macrophage tissues. This protein is known to be O-glycosylated and sulfated. Other names for this target antigen include SAG. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
