The 14B11 antibody reacts with a common epitope of Ly-49C/F/I/H family members also known as Ly-49 inhibitory receptors C, F, and I and activating receptor H. It does not react with other Ly-49 members (i.e., Ly-49A, B, D, and G). Ly-49 is a type-II transmembrane, disulfide-linked homodimer with C-type lectin extracellular domains that binds to MHC class I. Ly-49C/F/I/H is expressed on a subset of NK cells, NK-T cells and some CD8+ cells. Ly-49C/F/I, like other members of this family, inhibits NK cell activation through the recognition and interaction of certain MHC class I haplotypes on potential target cells. Ly-49C, Ly-49F, and Ly-49I contain an ITIM motif in their cytoplasmic tails, while Ly-49H lacks ITIM. Ly-49H is encoded by the Cmv1r gene, which promotes resistance to infection by mouse cytomegalovirus (CMV). BALB/c mice are reported to lack the Ly-49H and Ly-49I receptors. The 14B11 antibody, when bound to NK cells, is capable of inducing redirected cell lysis and blocking NK cell effector function.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: induction of redirected lysis1, and blocking2 of the binding of H-2d lymphoblasts to transfectants expressing Ly-49C, Ly-49F, and Ly-49I.
