    For Research Use only
  • Format
    Lyophilized
    Reconstitution
    It is not recommended to reconstitute to a concentration less than 100 μg/mL.
    Dissolve the lyophilized protein in ddH2O.
    Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
    Buffer
    Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.
    Handling Advice
    Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
    Storage
    4 °C/-20 °C/-80 °C
    Storage Comment
    Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
    Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
    Aliquots of reconstituted samples are stable at < -20°C for 3 months.
    Expiry Date
    3 months

    Background
    FcgammaRIIB is a low affinity receptor that recognizes the Fc portion of IgG. The human CD32 group consists of FcgammaRIIA, FcgammaRIIB, and FcgammaRIIC proteins that share 94-99% sequence identity in their extracellular domains but differ substantially in their transmembrane and cytoplasmic domains. FcgammaRII protein is expressed on cells of both myeloid and lymphoid lineages as well as on cells of non-hematopoietic origin. FcgammaRIIB has an intrinsic cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM) and delivers an inhibitory signal upon ligand binding. Ligation of FcgammaRIIB on B cells down-regulates antibody production and in some circumstances may promote apoptosis. Co-ligation of FcgammaRIIB on dendritic cells inhibits maturation and blocks cell activation. FcgammaRIIB may also be a target for monoclonal antibody therapy for malignancies. FcgammaRIIB plays an important negative-regulating role through modulating the signals from activation receptors.
