Additional Information: Interferon gamma FITC (Human) antibody

Antigen	Interferon gamma
Reactivity	Human
Antibody Type	Monoclonal
Format	Purified
Isotype	IgG1 »Matching secondary antibodies
Host	Mouse
Specificity	Interferon ? is a type-2 interferon that is produced mainly by T-cells and NK-cell upon cellular activation. Human CD8 T-cells, isolated from individuals after viral infection or vaccination, release IFN-? upon exposure to the corresponding viral antigens in vitro. The anti-Interferon ? Antibody (clone GZ4) reacts with intracellular human interferon ? expressed by activated T-cells and NK cells.

Application Details: Interferon gamma FITC (Human) antibody

Application	Immunofluorescence (IF), Flow Cytometry (FACS)
Application Notes	The GZ4 antibody permits the analysis of activated human T-cells and T-cell clones as well as NK cells using flow cytometry. To allow intracellular accumulation of IFN ? (prevent secretion), cells of interest can be pretreated with e.g. Brefeldin A (2 ?g/ml) for 18 hours before analyses. Results must be put within the context of other diagnostic tests as well as the clinical history of the patient by a certified professional before final interpretation. Analyses performed with this antibody should be paralleled by positive and negative controls. If unexpected results are obtained which cannot be attributed to differences in laboratory procedures, please contact us. Samples: under sterile conditions. Anticoagulation with EDTA or heparin is recommended. The samples should be stored at room temperature until used. For optimal results, samples should be processed and analyzed within 24 hours. Samples with high numbers of non-viable cells might cause false results, such cases require determination of cell viability with e.g. propidium iodide. All biological samples have to be handled with caution. Always consider them as potentially infective. Use appropriate precautions such as gloves, lab-coat, etc. Sensitivity: The sensitivity of GZ4 mAb is determined by staining well-defined blood samples from representative donors with serial-fold mAb dilutions to obtain a titration curve that allows relating the mAb concentration to the percentage of stained cells and geometric MFI (mean fluorescence intensity). For this purpose, a mAbconcentration range is selected to include both the saturation point (i.e. the mAb dilution expected to bind all epitopes on the target cell) and the detection threshold (i.e. the mAb dilution expected to represent the least amount of mAb needed to detect an identical percentage of cells). In practice, 50 ?l of leukocytes containing 107cells/ml are stained with 20 ?l mAb of various dilutions to obtain a titration curve and to identify the saturation point and detection threshold. The final concentration of the product is then adjusted to be at least 3-fold above the detection threshold. In addition and to control lot-to-lot variation, the given lot is compared and adjusted to fluorescence standards with defined intensity.
Conjugate	FITC
Purification	Chromatography
Buffer	PBS pH 7.2, 1% BSA, 0.05% NaN3
Storage	For stability reasons this monoclonal antibody solution contains sodium azide. These reagents should be stored at 2-8
Restrictions	For In Vitro Diagnostic Use. For professional users only. This reagent contains sodium azide. To avoid the development of hazardous conditions, reagents containing azide should be diluted in running water prior to be discarded. Similar to the work with other biological products, proper handling procedures are recommended.
