Background

Low affinity IgG Fc receptor gamma II (Fc-gamma II), also known as CD32, is a member of the immunoreceptor tyrosine-based activating/inhibitory motif (ITAM/ITIM) family. Fc gamma receptors play a critical role in immunity by linking the IgG antibody mediated response with the regulatory functions of the immune system (1). Three classes of Fc gamma receptor exist; Fc gamma RI (CD64, a high affinity receptor), Fc gamma RII, and RIII (CD32 and CD16 respectively, both low affinity receptors). Fc gamma RIIa is an activating receptor, while RIIb1, RIIb2, and RIIb3 are inhibitory receptors generated by alternative splicing (1-2). Fc gamma RIIa is critical for antigen-presenting-cell activation and Fc gamma RIIb downregulates B-cell functions (3). Fc gamma RIIb has also been known to block the inflammatory immune response in mice (4). Once phosphorylated on tyrosine residues, Fc gamma RIIb associates with SHIP to downregulate phagocytosis.

1. What is the difference between the Quantikine and Duoset ELISA kits?
   • Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
