Anti-GABPb antibodies enable researchers to detect and measure the GABPb antigen in biological samples. This target is a reported synonym of the GABPB1 gene, which encodes GA binding protein transcription factor subunit beta 1. This protein is known to function in the regulation of transcription, among other biological roles. The human version of GABPb has a canonical amino acid length of 395 residues and a protein mass of 42.5 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include BABPB2, E4TF1, and E4TF1-47. Indicated applications for GABPb antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
