IL-3 is a highly species-specific pleiotropic factor produced primarily by activated T cells though also by mast cells, keratinocytes, and astrocytes, which stimulates colony formation of megakaryocytes, neutrophils, and macrophages from bone marrow cultures. The BVD3-1F9 antibody can neutralize the bioactivity of natural or recombinant IL-3.

ICFC - Quality tested

Recommended Usage

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 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.

Excitation Laser
Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
Application Notes

ELISA1-3,6 or ELISPOT4 Detection: The biotinylated BVD3-1F9 antibody is useful as a detection antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with purified BVD8-3G11 (Cat. No. 500502) antibody as the capture antibody.
Flow Cytometry: The fluorochrome-labelled BVD3-1F9 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IL-3 -producing cells within mixed cell populations.
