BD OptiBuild™ BV750 Mouse Anti-Human BAH-1

The BAH-1 monoclonal antibody was raised against human megakaryocytic cells. It was originally proposed that clone BAH-1 was specific for human CD110, also known as c-Mpl or TPO-R. Data has emerged to suggest that BAH-1 antibody may not recognize CD110. However, there is strong evidence that it recognizes an antigen that is highly expressed on human Megakaryocyte-Erythroid Progenitor (MEP) cells. In combination with CD71, BAH-1 expression has been used to distinguish subsets of Hematopoietic Stem Cells and Myeloid Progenitors in human fetal liver, cord blood, and adult bone marrow. BAH-1 antibody can induce megakaryocytopoiesis of both mouse and human bone marrow cells in vitro.

The antibody was conjugated to BD Horizon™ BV750 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 750-nm. BD Horizon Brilliant BV750 can be excited by the violet laser (405 nm) and detected with a 750/30 nm filter with a 740 nm long pass. Due to spectral differences between labeled cells and beads, using BD™ CompBeads can result in incorrect spillover values when used with BD Horizon BV750 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended.
