Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 ?g per million cells in 100 ?L volume. It is recommended that the reagent be titrated for optimal performance for each application.

* Spark NIR? 685 has a maximum excitation of 665 nm and a maximum emission of 685 nm.

ELISA^1-4,11,14 or ELISPOT⁵ Detection: The biotinylated XMG1.2 antibody is useful as a detection antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with purified R4-6A2 antibody (Cat. No. 505702/505706) as the capture antibody and recombinant mouse IFN-? (Cat. No. 575309) as the standard.
ELISA or ELISPOT Capture: The purified XMG1.2 antibody is useful as a capture antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with biotinylated R4-6A2 antibody (Cat. No. 505704) as the detection antibody and recombinant mouse IFN-? (Cat. No. 575309) as the standard. The LEAF? purified antibody is suggested for ELISPOT capture (Cat. No. 505812).
Flow Cytometry^7,8,12,13,16: The fluorochrome-labeled XMG1.2 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IFN-?-producing cells within mixed cell populations.
Neutralization^1-3,9,10: The XMG1.2 antibody can neutralize the bioactivity of natural or recombinant IFN-?. The LEAF? purified antibody (Endotoxin <0.1 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for neutralization of mouse IFN-? bioactivity in vivo and in vitro (Cat. No. 505812). For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF? purified antibody (Cat. No. 505834) with a lower endotoxin limit than standard LEAF? purified antibodies (Endotoxin <0.01 EU/?g).
Additional reported applications (for the relevant formats) include: Western blotting, immunohistochemical staining of frozen tissue sections^6,22,23, and immunocytochemistry.
Note: For testing mouse IFN-? in serum, plasma or supernatant, BioLegend's ELISA Max? Sets (Cat. No. 430801 to 430806) are specially developed and recommended.
