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.

* PE/Dazzle? 594 has a maximum excitation of 566 nm and a maximum emission of 610 nm.

ELISA^1,2,10,13 or ELISPOT⁵ Capture: The purified 11B11 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with the biotinylated BVD6-24G2 antibody (Cat. No. 504202) as the detecting antibody and recombinant mouse IL-4 (Cat. No. 575609) as the standard. The LEAF? purified antibody is suggested for ELISPOT capture.
Neutralization^1-2,9,12: The 11B11 antibody can neutralize the bioactivity of natural or recombinant IL-4. The LEAF? purified antibody (Endotoxin <0.1 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for neutralization of mouse IL-4 bioactivity in vivo and in vitro (Cat. No. 504108).
Additional reported applications (for the relevant formats) include: immunoprecipitation¹⁶, immunohistochemical staining of formalin-fixed paraffin-embedded tissue sections⁸ and paraformaldehyde-fixed, saponin-treated frozen tissue sections^6,7, and immunocytochemistry⁴.
Note: For testing mouse IL-4 in serum, plasma or supernatant, BioLegend's ELISA Max? Sets (Cat. No. 431101 to 431106) are specially developed and recommended.
