CD1D
Reactivity: Human
WB
Host: Mouse
Polyclonal
unconjugated
Application Notes
Reported applications include immunoprecipitation, blocking of in vitro antigen-mediated stimulation of NK1+T cells, blocking of in vitro responses of some T cells to CD1d1, (possibly to the beta2m-associated form of CD1d, but not to beta2m-independent CD1d4), and in vivo inhibition of TGF-beta2 production. mAb 3C11 (Cat. no. 559871) has been reported to inhibit responses of some T cells to both beta2m-associated and beta2m-independent forms of CD1d.

The 1B1 antibody reacts with CD1d, a 48-kDa glycoprotein with structural homology to the major histocompatibility complex (MHC) class I molecules. The structure, expression, and functions of CD1 antigens are complex and have been reviewed. mAb 1B1 detects CD1d at varying levels on most types of bone marrow and peripheral leukocytes and on epithelial, dendritic, and lymphoid cells in the thymus. It appears to recognize CD1d only in association with beta2m. CD1d has been reported to be expressed by gastrointestinal tract epithelium and in the cytoplasm of hepatocytes as detected via immunohistochemical staining of frozen sections with mAb 3C11 (Cat. No. 559871, for the purified antibody), suggesting a possible role for CD1d in mucosal immunity. However, CD1d expression was not detectable, via flow cytometry, on intestinal epithelial cells in studies using the anti-CD1d mAbs 3C11, 1B1, and 9C7. The 1B1 antibody competes with mAb 3C11 in binding to mouse splenocytes. Synonyms: CD1.1, Ly-38
