Description

Rat Monoclonal Antibody

Description: The monoclonal antibody 42D1 recognizes the CD85d protein also known as ILT4, LIR-2. It is a member of the ILT (immunoglobulin-like transcript)/ LIR (leukocyte Ig-like receptor), MIR (monocytes Ig-like receptor) family. CD85d is a 110 kDa single transmembrane receptor with 3 Ig-like domains and a long cytoplasmic domain containing ITIMs (immunoreceptor tyrosine-based inhibitory motifs). Expression is confined to monocytes, macrophages and dendritic cells. The ligand for CD85d is non-classical class I HLA-G, -B and G1. Upon ligand binding, tyrosine phosphatase SHP-1 interacts with the ITIM. Interaction of HLA-G with ILT4/CD85d is thought to contribute to tolerance during fetal implantation. Additionally, it is the levels of ILT3 and ILT4 on DCs that suggests a role in organ allograft rejection. Crosslinking of the receptor with the monoclonal antibody 42D1 inhibits calcium flux as well as enhancing HLA-G tetramer staining and restoring the stimulating activity of tolerogenic DC. Applications Reported: This 42D1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 42D1 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.25 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....

CD85d, also known as LILRB2 or ILT4, is a member of the immunoglobulin-like transcript (ILT), leukocyte Ig-like receptor (LIR), and monocyte Ig-like receptor (MIR) family. It is a 110 kDa single transmembrane receptor with three Ig-like domains and a long cytoplasmic domain containing immunoreceptor tyrosine-based inhibitory motifs (ITIMs). CD85d is expressed on monocytes, macrophages, and dendritic cells. The receptor binds to non-classical class I molecules such as HLA-G, -B, and G1. Upon ligand binding, the tyrosine phosphatase SHP-1 interacts with the ITIMs, transducing a negative signal that inhibits immune response stimulation. This interaction is thought to contribute to tolerance during fetal implantation and plays a role in controlling inflammatory responses and cytotoxicity, helping to focus the immune response and limit autoreactivity. CD85d is also involved in organ allograft rejection, with the levels of ILT3 and ILT4 on dendritic cells suggesting its role in this process. The LILRB2 gene, located in a gene cluster at chromosomal region 19q13.4, encodes multiple transcript variants with different isoforms, highlighting its complexity and importance in immune regulation.
