FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation1.

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 ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Ly-49A is a 44 kD member of the C-type lectin/Ly-49 family proteins. It is a type-II transmembrane, disulfide-linked homodimer with C-type lectin extracellular domains. Ly-49A is present on a subset of NK and NK-T cells. Ly-49A, 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. The Ly-49A receptor recognizes H-2Dd and H-2Dk, triggering phosphorylation of the ITIM motif in the cytoplasmic domain and recruitment of SHP-1 and SHP-2. The A1/Ly49A antibody preferentially reacts with CRD of Ly-49AB6 alloantigen and has also shown cross-reaction with Ly-49ANOD, Ly-49PNOD and Ly-49P129/J.
