Allophycocyanin (APC) is a stable and highly soluble phycobiliprotein that provides maximal absorbance and fluorescence without susceptibility to internal or external fluorescence quenching, thus providing exceptional quantum yields and molar extinction coefficients.
CD16 (FCGR3A) is a 50-65 kDa cell surface molecule that exists in two forms - a transmembranous form expressed by NK cells and some T cells, and a phosphatidylinositol linked form expressed by granulocytes. CD16 is a low affinity receptor for IgG (FcR III), and is an important receptor mediating ADCC by NK cells. Human CD16 is expressed in two forms – FCGR3A and FCGR3B. FCGR3A is associated with the FcepsilonRI-gamma subunit and is responsible for antibody-dependent NK cell cytotoxicity. Mast cell FCGR3A is associated, with FcepsilonRI-beta subunit. Besides IgG, FCGR3A can be triggered also by oligomeric IgE. FCGR3B is a GPI-linked monomeric receptor expressed on neutrophils and is involved in their activation and induction of a pro-adhesive phenotype. Diseases associated with CD16 dysfunction include immunodeficiency 20 and systemic lupus erythematosus.
