Invitrogen™ CD85j (ILT2) Monoclonal Antibody (HP-F1), PE-eFluor™ 610, eBioscience™, Invitrogen™

Beschreibung

Description: The monoclonal antibody HP-F1 recognizes CD85j, also known as ILT2, LILRB1, and LIR1. CD85j is a member of the ILT (immunoglobulin-like transcript)/LIR (leukocyte Ig-like receptor)/MIR (monocyte Ig-like receptor) family. CD85j is a single transmembrane glycoprotein with a long cytoplasmic domain containing 4 ITIMs which signal through interactions with SHP-1. Expression is found on myeloid cells (monocytes and dendritic cells) and some lymphoid cells including, subsets of NK, T and B cells. Expression has been correlated with leukemias such as ALL and CLL. Expression on CD8+ cells correlates with effector cell function and plays an important role in viral infections, including HIV, Ebstein Barr and CMV. The ligands for CD85j are MHC Class I molecules such as HLA-G, A, F, B27, E and F. Applications Reported: This HP-F1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This HP-F1 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PE-eFluor 610 can be excited with laser lines from 488-561 nm and emits at 607 nm. We recommend using a 610/20 band pass filter (equivalent to PE-Texas Red).

CD85j, also known as a member of the leukocyte immunoglobulin-like receptor (LIR) family, is a single transmembrane glycoprotein with a long cytoplasmic domain containing four immunoreceptor tyrosine-based inhibitory motifs (ITIMs). These motifs signal through interactions with SHP-1, transducing negative signals that inhibit immune response stimulation. CD85j is expressed on myeloid cells such as monocytes and dendritic cells, as well as on subsets of lymphoid cells including NK, T, and B cells. The expression of CD85j is correlated with leukemias such as acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL). On CD8+ cells, CD85j expression is associated with effector cell function and plays a significant role in viral infections, including HIV, Epstein-Barr virus, and cytomegalovirus (CMV). CD85j binds to MHC class I molecules, including HLA-G, A, F, B27, E, and F, on antigen-presenting cells. The receptor helps control inflammatory responses and cytotoxicity, focusing the immune response and limiting autoreactivity. CD85j belongs to the subfamily B class of LIR receptors, which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and multiple transcript variants encoding different isoforms have been identified for this gene. Its gene is located in a cluster at chromosomal region 19q13.4.
