The MIH61 monoclonal antibody specifically binds to TLT-2 (TREM-like transcript 2 protein) which is also known as TREML2 (Triggering receptor expressed on myeloid cells-like 2). TLT-2 is a 33 kDa type I transmembrane protein that belongs to the TREM family. It consists of a single extra-cellular Ig-like V-type domain, a transmembrane segment and a cytoplasmic tail. TLT-2 is expressed on B cells, granulocytes, monocytes/macrophages and a fraction of peripheral blood T cells. TLT-2 expression on neutrophils and macrophage is reportedly upregulated in response to inflammatory conditions in vivo. TLT-2 plays important roles in innate and adaptive immunity. It acts as an engulfment receptor for apoptotic cells and can enhance the activation of T cells. The MIH61 antibody reportedly does not recognize mouse TLT-2.
This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers. BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.
