Anti-collagen type XXIII alpha 1 antibodies are used in antigen-specific immunodetection in biological samples. The target collagen type XXIII alpha 1 is a known alias name of the protein collagen type XXIII alpha 1 chain, encoded by the COL23A1 gene in humans. This 540-amino acid residue protein is known to be involved in extracellular matrix organization, among other biological processes. It is localized to the cell membrane of the cell and features cleaved post-translational modifications.
