The HTF-1 monoclonal antibody specifically binds to CD142. CD142 is a 45-47 kDa, single chain, type I transmembrane glycoprotein also known as Tissue Factor (TF). CD142 has been referred in the literature as coagulation Factor III or thromboplastin and it is expressed on activated endothelial cells and lipopolysaccharide (LPS)-stimulated monocytes/macrophages. TF associates with factor VIIa to form a complex and acts as an enzyme that initiates the blood coagulation cascade. It is known as the major initiator of clotting in normal hemostasis. CD142 can be induced by various inflammatory mediators in monocytes and vascular endothelial cells. This antibody is useful in inflammation, thrombosis and hemostasis research.
The antibody was conjugated to BD Horizon™ BUV563 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 which has an Ex Max of 348 nm and an acceptor dye. The tandem has an Em Max at 563 nm. BD Horizon BUV563 can be excited by the 355 nm ultraviolet laser. On instruments with a 561 nm Yellow-Green laser, the recommended bandpass filter is 585/15 nm with a 535 nm long pass to minimize laser light leakage. When BD Horizon BUV563 is used with an instrument that does not have a 561 nm laser, a 560/40 nm filter with a 535 nm long pass may be more optimal. Due to the excitation and emission characteristics of the acceptor dye, there may be spillover into the PE and PE-CF594 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
