Leukocyte Immunoglobulin Like Receptor B1 (LILRB1) is a member of the leukocyteimmunoglobulinlike receptor (LIR) family. LILRB1is expressed on immune cells, binds to MHC classI molecules on antigen-presenting cells and transduces a negative signal that inhibits stimulation of an immuneresponse. LILRB1 controls inflammatory responses and cytotoxicity to help focus the immune responseand limit autoreactivity. LILRB1 is also expressed on the surface of B cells and monocytes, subsets of NKcells, gamma δ T cells,memory/effector CD8+ T cells and monocyte-derived dendritic cells.
LILRB1 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 446 amino acids (24-461 a.a) and having a molecular mass of 48.5kDa.
LILRB1 is fused to an 8 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
The LILRB1 solution (0.25mg/ml) contains 10% glycerol and Phosphate-Buffered Saline (pH 7.4).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
Biological activity is > 50%. It is defined by the ability of the immobilized protein to support the adhesion of HSB2 human peripheral blood acute lymphoblastic leukemia cells, while the cells are added to LILRB1 coated plates at 5ug/ml.
