Background

Spi-B is a 33-45 kDa member of the ets family of transcription factors. It is found in hematopoietic cells such as B cells and plasmacytoid dendritic cells (DC). In transitional B cells, Spi-B promotes their differentiation into follicular (naïve) B cells. In hematopoietic stem cells, Spi-B stimulates the generation of IFN-producing plasmacytoid DC at the expense of T, B and NK cell development. The 262 amino acid (aa) human Spi-B contains a dual transactivation region (aa 1-62) and an ets DNA-binding domain (aa 169-252). One 177 aa variant diverges after aa 162. Over aa 7-115, human Spi-B shares 72% and 70% aa identity with mouse and rat Spi-B, respectively.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
