The hTNFR-RP-M12 monoclonal antibody specifically recognizes the extracellular domain of the 61 kDa receptor for the human cytokines, LTα1β2 and LIGHT. This receptor is referred as the Lymphotoxin β Receptor (LTβR). LTβR is encoded by TNFRSF3. LTβR was previously known as TNFRIII and TNF receptor-related protein (TNFRrp). LTβR is a type I transmembrane glycoprotein and member of the TNF Receptor Superfamily. LTβR are expressed on stromal cells in lymphoid tissue, normal dermal fibroblasts, bronchial airway epithelial cells and in a variety of adherent cell lines including FDC-1, U937, HT-29, HeLa and HEK 293 cells. LTβR are absent on human peripheral blood T and B cells and expressed at low levels by monocytes.
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.
