Background
Fc gamma receptor IIIA (RIIIA), also called CD16a, is an activating natural killer (NK) cell receptor that binds the Fc portion of immunoglobulin G (IgG) antibodies and is responsible for eliciting a host defense against microbial pathogens (1). Fc gamma RIIIA/CD16a belongs to the Fc gamma RIII (CD16) subclass of Fc gamma receptors (1,2). The two other subclasses of receptors are Fc gamma RI (CD64) and Fc gamma RII (CD32) (1,2). The two form of Fc gamma RIII are Fc gamma RIIIA (CD16a) and Fc gamma RIIIB (CD16b), which are encoded by two different homologous genes, FCGR3A and FCGR3B, respectively (1-3). The human Fc gamma RIIIA protein is 254 amino acids (aa) in length with a theoretical molecular weight (MW) of 29 kDa (1,4,5). CD16a contains five glycosylation sites, two disulfide bonds, and two Ig-like C2 domains (4). Fc gamma RIIIA/CD16a is expressed as a transmembrane protein on NK cells and on a subset of monocytes, macrophages, CD4+ T cells, basophils, and mast cells (1-3). The soluble form of CD16 (sCD16) is often produced following exposure to inflammatory signals and protein shedding via metalloproteinases (3). Reduced sCD16 levels have been found in patients with multiple myeloma (3).
Activating NK cell receptor function has been harnessed for its potential in tumor immunotherapy (5). One immunotherapy strategy is using bi- and tri-specific NK cell engagers (BiKE and TriKE) to target the Fc gamma RIIIA/CD16a receptor with tumor-associated antigens to stimulate a cytotoxic response and mount an attack on tumor cells (5). CD16a is also capable of antibody dependent cellular cytotoxicity (ADCC) through recognition of antibodies bound to target cells (5-6). CD16-induced NK cell activation allows for NK co-receptor expression including stimulatory receptors like CD137 or inhibitory receptors like TIGIT and PD-1, which serve as additional regulatory checkpoints during ADCC (6). Therapeutic antibodies for cancer treatment like rituximab or trastuzumab can be recognized by Fc gamma RIIIA/CD16a to activate NK cell-mediated killing of tumor cells (5-6).

I am interested in developing a surrogate ADCC assay (FC gamma III a binding assay) for which, I would require a CD16 Recombinant Protein as an antigen and Anti-Human IgG (Fc specific) as a secondary antibody as I am planning to perform this assay in an ELISA format. With this brief description, could you please suggest me the right CD16 Recombinant Protein among the three listed products in your web site (www.novusbio.com/proteins/cd16). Appreciate if you can share a reference article, where the use of this protein is cited.
- The right CD16 protein for you depends on what sort of functionality you require for your assay. H00002214-P01 is made by a Taiwanese company called Abnova and we distribute it for them. They do not test the activity of their recombinant proteins. The proteins are produced in a cell-free wheat germ system with an N-terminal 26kDa GST-tag. Due to this expression system, in our experience, the proteins do not always undergo the same folding and post-transnational modifications they might undergo in an endogenous cell. Because of this, we do not recommend this protein for use in functional assays and do not guarantee them for this use. They are mainly intended for use in Western Blots and ELISA as a positive control with their antibody. NBP1-98908 is produced in E. coli and contains a His-tag and it also not guaranteed for functionality but may be due to its E. coli expression system. H00002214-G01 is also an Abnova and is made in their cell-free wheat germ expression system with proprietary liposome technology. This is a recently developed system by them and is intended to help the proteins fold and maintain functionality. Which protein would be best for you depends on what you require for your assay. Here is a link to our antibodies to the Fc region of human IgG. The best antibody for you will depend on what you would like to use for detection.
