SPIB Antibody (PA5-121102) in WB
Western blot analysis of SPIB in extracts of Raji cells. Samples were incubated with SPIB Polyclonal antibody (Product # PA5-121102) using a dilution of 1:1,000, followed by HRP Goat Anti-Rabbit IgG (H+L) at a dilution of 1:10,000. Lysates/proteins: 25 µg per lane. Blocking buffer: 3% nonfat dry milk in TBST. Detection: ECL Basic Kit. Exposure time: 60s.

Target Information
Spi-B is a transcription factor belonging to a subfamily of ETS transcription factors with a conserved ETS domain that mediates specific DNA binding. Spi-B may form homotypic interactions and is known to interact with IRF4, CREBBP, EP300, SPI1/PU.1 related, JUN and TBP. As a sequence specific transcriptional activator it binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA-3') that can act as a lymphoid-specific enhancer. Two isoforms of Spi-B are reported. Spi-B is usually expressed in plasmacytoid dendritic cells (pDCs), also known as type 2 DC precursors (pre-DC2) or natural interferon (IFN)-producing cells and promotes their development and block viral replication. Spi-B is not expressed in T-cells or granulocytes but may be present in stem cell populations of the liver and B-cells where it helps in B-cell receptor (BCR) signaling, normal B-cell development and antigenic stimulation.
