Formulation
This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added.
Product Preparation
Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Storage and Handling
Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Description
Specificity
Clone 3G8 recognizes an epitope on human CD16. This clone also cross-reacts with non-human primate CD16.
Antigen Distribution
CD16 is expressed on NK cells, activated monocytes, macrophages, neutrophils, and placental trophoblasts.
Background
CD16 antibody, 3G8, recognizes human CD16, also known as low-affinity IgG receptor III (FcγRIII). There are two distinct forms of CD16, CD16a (FcγRIIIa) and CD16b (FcγRIIIb). CD16a is a 50-65 kDa heterooligomeric polypeptide-anchored transmembrane protein expressed by NK cells, macrophages, and subsets of monocytes1. CD16b is a 48 kDa monomeric glycosylphosphatidylinositol (GPI)-anchored protein expressed on neutrophils1. Upon binding to the Fc portion of IgG or IgG-antigen complex, both CD16 isoforms induce signaling cascades resulting in multiple functions, including phagocytosis, cytokine release, proliferation, degranulation, and antibody dependent cell-mediated cytotoxicity (ADCC)2.
