Description

The monoclonal antibody 51.1 reacts with human CD1d, a member of the CD1 family with similarity to the non-polymorphic MHC Class I-like molecules. CD1d is a highly conserved single transmembrane receptor of the Immunoglobulin Superfamily. CD1d can associate withβ-microglobulin another feature showing similarity to MHC class I molecules, but can also exist as a nonglycosylated protein not in association with β microglobulin. This suggests different control mechanisms for presenting glycolipid containing molecules to CD1d reactive NKT cells. Expression of CD1d is found on B cells of the periphery, in resting monocytes and cortical thymocytes. On intestinal epithelial cells (IEC) expression is polarized. Expression can also be found at low levels intracellularly in hepatocytes. In HCV (hepatitis C virus) livers, CD1d is highly expressed compared to normal controls.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This 51.1 antibody has been reported for use in flow cytometric analysis.

Applications Tested

This 51.1 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 20 μl (0.125 μg) per million cells in a 100 μl total staining volume.
