Transcription factor PU.1 (SPI1) is an ETS-domain transcription factor that activates gene expression during myeloid and B-lymphoid cell development. The nuclear protein binds to a purine-rich sequence known as the PU-box found near the promoters of target genes, and regulates their expression in coordination with other transcription factors and cofactors. SPI1 can also regulate alternative splicing of target genes. Multiple transcript variants encoding different isoforms have been found for SPI1.
Human Transcription factor PU.1 (SPI1) ELISA Kit employs a two-site sandwich ELISA to quantitate SPI1 in samples. An antibody specific for SPI1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySPI1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SPI1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SPI1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
