The islet cell autoantigen 1, 69kDa ELISA kits listed below utilize specific antibodies for the plate-based assay of islet cell autoantigen 1, 69kDa in various samples. islet cell autoantigen 1, 69kDa is another term for the ICA1 gene, which encodes the protein, islet cell autoantigen 1 in humans. The target protein is believed to play a role in neurotransmitter secretion. Structurally, the ICA1 protein is 483 amino acid residues in length and 54.6 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the membrane, cytoplasmic vesicles, golgi, and cytoplasm of the cell. In terms of tissue specificity, it is noted to be expressed abundantly in pancreas, heart and brain with low levels of expression in the lung, kidney, liver and thyroid. Other names for this target antigen include ICA69, ICA69, and ICAp69. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
