Anti-Hlxb9 antibodies are used in antigen-specific immunodetection in biological samples. The target Hlxb9 is a known alias name of the protein motor neuron and pancreas homeobox 1, encoded by the MNX1 gene in humans. This 401-amino acid residue protein is known to be involved in nervous system development, among other biological processes. It is localized to the nucleus of the cell. In terms of tissue expression, it is reported to be expressed in lymphoid and pancreatic tissues. Other synonyms for Hlxb9 include HB9 and HB9.
