CD32B Protein, Human, Recombinant (His)

CD32B Protein, Human, Recombinant (His)

产品编号 TMPJ-00192
别名: FCG2, IgG Fc Receptor II-b, CDw32, Low Affinity Immunoglobulin Gamma Fc Region Receptor II-b, Low Affinity Immunoglobulin γ Fc Region Receptor II-b, FCGR2B, Fc-γ-RIIb, FcRII-b, Fc-Gamma RII-b, Fc-Gamma-RIIb, Fc-γ RII-b, IGFR2, CD32

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

缓冲液 Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM PB, 150 mM NaCl, pH 7.2.
复溶方法 Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储

Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.

运输方式

In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice.
