Anti-PBX homeobox 2 antibodies are used for the immunodetection of the protein encoded by the PBX2 gene. In humans, the canonical protein has a reported length of 430 amino acid residues and a mass of 45.9 kDa. Its subcellular localization is in the nucleus. It is ubiquitously expressed across many tissue types. A member of the TALE/PBX homeobox protein family, it is reported to be a transcriptional activator that binds the sequence 5'-ATCAATCAA-3'. Other names for this target antigen include HOX12, PBX2MHC, pre-B-cell leukemia transcription factor 2, XXbac-BPG300A18.13, homeobox 12, and G17. Gene orthologs have been identified in the mouse, rat, bovine, frog and chimpanzee species. A number of PBX homeobox 2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
