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 ≤ 0.5 µg per 106 cells in 100 µl volume. It is 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.

- Application Notes
Flow Cytometry3,5: The fluorochrome-labeled C11.5 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IL-12 p40 (monomeric, heterodimeric, homodimeric) -producing cells within mixed cell populations. For intracellular cytokine staining protocol, please visit www.biolegend.com and click on the support section.
Neutralization6: The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 501813).
Additional reported applications (for the relevant formats) include: Western blotting, ELISA Capture1,2, ICFC Blocking, immunohistochemical staining4 of paraformaldehyde-fixed, saponin-treated tissue frozen sections, and immunocytochemistry.
Note: For testing human IL-12/IL-23 p40 (monomer, dimer) in serum or plasma, BioLegend's ELISA Max™ Sets (Cat. No. 430701 to 430706) are specially developed and recommended. For testing human IL-12 p70 in serum or plasma, BioLegend's ELISA Max™ Sets (Cat. No. 431701 to 431706) are specially developed and recommended.
