Fc OxyBURST™ Greenアッセイ試薬は、ジクロロジヒドロフルオレセイン(H2DCF)と共有結合され、精製ウサギポリクローナル抗BSA抗体と複合化されたウシ血清アルブミン(BSA)で構成されています。この免疫複合体がFc受容体に結合すると、非蛍光H2DCF分子が食胞内に取り込まれ、その後で緑色蛍光の2''7'-ジクロロフルオレセインに酸化されます。

Abstract
The phosphoinositide-binding protein p40phox activates the NADPH oxidase during FcgammaIIA receptor-induced phagocytosis.
Authors:Suh CI, Stull ND, Li XJ, Tian W, Price MO, Grinstein S, Yaffe MB, Atkinson S, Dinauer MC
Journal:J Exp Med
PubMed ID:16880255
'Superoxide produced by the phagocyte reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase is essential for host defense. Enzyme activation requires translocation of p67(phox), p47(phox), and Rac-GTP to flavocytochrome b558 in phagocyte membranes. To examine the regulation of phagocytosis-induced superoxide production, flavocytochrome b558, p47(phox), p67(phox), and the FcgammaIIA receptor were expressed ... More
Severe impairment in early host defense against Listeria monocytogenes in mice deficient in acid sphingomyelinase.
Authors:Utermöhlen O, Karow U, Löhler J, Krönke M
Journal:J Immunol
PubMed ID:12594290
'The phagolysosomal compartment is crucial for the defense against infection with intracellular pathogens. Within this compartment, the TNF- and IFN-gamma-responsive acid sphingomyelinase (ASMase) generates the signaling molecule ceramide, resulting in the activation of proteases like cathepsin D. To investigate the possible role of ASMase as a mediator of the antibacterial ... More
Quantitative multiwell myeloid differentiation assay using dichlorodihydrofluorescein diacetate (H2DCF-DA) or dihydrorhodamine 123 (H2R123).
Authors:Trayner ID, Rayner AP, Freeman GE, Farzaneh F
Journal:J Immunol Methods
PubMed ID:7594627
'It is well established that the fluorescent probes dichlorodihydrofluorescein diacetate (H2DCF-DA) and dihydrorhodamine 123 (H2R123) can be used to detect the respiratory burst response of mature myeloid cells. We describe a simple, fast and quantitative assay for myeloid differentiation based on the oxidation of these probes, which can be performed ... More
A cytosolic calcium transient is not necessary for degranulation or oxidative burst in immune complex-stimulated neutrophils.
Authors:Seetoo KF, Schonhorn JE, Gewirtz AT, Zhou MJ, McMenamin ME, Delva L, Simons ER
Journal:J Leukoc Biol
PubMed ID:9307071
'Receptor-mediated activation of neutrophils (PMN) initiates possibly interdependent events, including a rapid transient increase in [Ca2+]i, implicated as a second messenger. To investigate whether this transient is required for eventual degranulation, PMN were incubated with an intracellular Ca2+ chelator (BAPTA), then exposed to chemotactic peptide [N-formyl-methionyl-leucyl-phenylalanine (fMLP)l with or without ...

Fluorescent probes for living cells.
Authors:Johnson I
Journal:Histochem J
PubMed ID:10188922
'The functional characteristics of fluorescent probes used for imaging and measuring dynamic processes in living cells are reviewed. Initial consideration is given to general design requirements for delivery, targeting, detectability and fluorescence readout, and current technologies for attaining them. Discussion then proceeds to the more application-specific properties of intracellular ion ... More
