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 10⁶ cells in 100 ?l volume. It is highly recommended that the reagent be titrated for optimal performance for each application.

* Pacific Blue? has a maximum emission of 455 nm when it is excited at 405 nm. Prior to using Pacific Blue? conjugate for flow cytometric analysis, please verify your flow cytometer's capability of exciting and detecting the fluorochrome.

ELISA Detection^1-3 or ELISPOT Detection^4-6: The biotinylated JES6-5H4 antibody is useful as a detection antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with the purified JES6-1A12 antibody (Cat. Nos. 503701 & 503702) as capture antibody and recombinant mouse IL-2 (Cat. No. 575409) as the standard.
Flow Cytometry^8-10: The fluorochrome-labeled JES6-5H4 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IL-2 -producing cells within mixed cell populations.
Neutralization^1,7: The Ultra-LEAF? purified antibody (Endotoxin in vivo and in vitro (Cat. No. 503845-503850)) is recommended for neutralization.
Additional reported applications (for the relevant formats) include: immunoprecipitation¹, immunohistochemical staining of paraformaldehyde-fixed, saponin-treated frozen tissue sections², in vivo capture⁷, and immunocytochemistry.
Note: For testing mouse IL-2 in serum, plasma or supernatant, BioLegend's ELISA MAX? Sets (Cat. No. 431001 & 431004) are specially developed and recommended.
