General description

ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Target description

Low affinity immunoglobulin g Fc region receptor II-b/c (UniProt: P31994/ P31995; also known as IgG Fc receptor II-b/c, CDw32, Fc-gamma RII-b/c, Fc-gamma-RIIb-c, FcRII-b/c, CD32) is encoded by the FCGR2B/C (also known as CD32, FCG2, IGFR2) gene (Gene ID: 2213/9103) in human. FcRII-b/c are single-pass type 1 membrane proteins that are synthesized with a signal peptide (aa 1-42), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 43-217 for FcRII-b and 43-223 for FcRII-c), a transmembrane domain (aa 218-240 for FcRII-b and 224-246 for FcRII-c) and a cytoplasmic domain (aa 241-310 for FcRII-b and 247-323 for FcRII-c). They also contain two Ig-like C2 domains and an ITIM motif, which is involved in triggering cell activation upon receptors aggregation. This motif can bind the SH2 domain of several SH2-containing phosphatases. FcRII-b/c can undergo phosphorylation by Src-type tyrosine kinases, such as LYN and BLK. This IgG Fc receptor is the most broadly distributed Fc-g receptor and is reported to be expressed in monocyte, neutrophils, macrophages, basophils, eosinophils, Langerhans cells, B-cells, platelets cells and placenta (endothelial cells). However, it is not detected in natural killer cells. It is involved in a variety of effector and regulatory functions such as phagocytosis of immune complexes and modulation of antibody production by B-cells. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
