Anti-collagen type XXVI alpha 1 antibodies enable researchers to detect and measure the collagen type XXVI alpha 1 antigen in biological samples. This target is a reported synonym of the COL26A1 gene, which encodes collagen type XXVI alpha 1 chain. The human version of collagen type XXVI alpha 1 has a canonical amino acid length of 441 residues and a protein mass of 45.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the extracellular matrix and is secreted of cells and notably expressed in the colon and skin.
