These pre B cell leukemia homeobox 4 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. pre B cell leukemia homeobox 4 is an alias of the human PBX4 gene, which encodes the protein, PBX homeobox 4. Notably, pre B cell leukemia homeobox 4 is known to play a role in organ morphogenesis and brain development, among other functions. The PBX4 protein is described to be 374 amino acid residues in length and 40.9 kilodaltons in mass. It is localized to the nucleus of the cell. Other names for this target antigen include pre-B-cell leukemia transcription factor 4, homeobox protein PBX4, and pre-B-cell leukemia homeobox 4.
