产品特性
- The CD1d:Ig fusion protein consists of the extracellular major histocompatibility complex (MHC) class I-like domains of the mouse CD1d molecule fused with the VH regions of mouse IgG1 (see figure). Like MHC class I molecules, the CD1d noncovalently associates with β2 Microglobulin (β2M). For this reason, BD Pharmingen DimerX consists of recombinant CD1d:Ig and β2M. Recombinant CD1d molecules, like the DimerX fusion protein, are useful for studying Natural Killer T (NKT)-cell function by immunofluorescent staining and flow cytometric analysis of antigen-specific NKT cells. The mouse CD1D1 gene encodes a non-polymorphic cell-surface protein that plays a role in antigen presentation to CD1d-restricted NKT cells. Like the MHC class I molecules, CD1d associates noncovalently with β2M and is capable of binding and presenting lipid antigens. While the natural ligand for CD1d is presently unknown, it is well documented that CD1d can bind and present the glycolipid, α-galactosyl ceramide (α-GalCer*), a glycosphingolipid from the marine sponge. Glycosylphosphatidylinositol (GPI) has also been identified as a major CD1d-associated component. Antigenic glycolipids such as α-GalCer associated with the CD1d molecule are presented and specifically recognized by NKT cells expressing a highly conserved TCR, Vα 14Ja281, paired with diverse β chains such as Vβ 8.2 and Vβ 7. Mouse CD1d:Ig shows differential staining intensities on Vα 14Ja281+ cells, based on the Vβ chain present, with Vβ 8.2+ cells predominantly showing higher intensities than Vβ 7+ cells. The function and lineage marker expression of NKT cells and their interaction with CD1d has been recently reviewed.

纯化方法
- The mouse CD1d:Ig fusion protein was expressed together with mouse β2M in the mouse plasmacytoma cell line, J558L (ATCC TIB-6). The CD1d:Ig and β2M polypeptide chains are associated noncovalently as a consequence of their coexpression within J558L cells. The CD1d:Ig fusion protein was purified from tissue culture supernatant by affinity chromatography. The purity of the preparation was confirmed by SDS-PAGE. The CD1d:Ig has been tested by ELISA to verify the fusion protein.
