The RMT4-54 monoclonal antibody specifically binds to TIM-4. TIM-4 is encoded by Timd4 (T cell immunoglobulin and mucin domain containing 4). TIM-4 is also known as Spleen, mucin-containing, knockout of lymphotoxin protein (SMUCKLER). TIM-4 is a single-pass type I membrane transmembrane glycoprotein belonging to the TIM family of the immunoglobulin superfamily. TIM-4 is expressed by macrophages and at low levels by dendritic cells. TIM-4 is a phosphatidylserine receptor that enhances the phagocytosis of apoptotic cells. It can serve as a receptor for TIM-1, also known as the Hepatitis A virus cellular receptor 1 (Havcr1).
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.
