BV421 Mouse Anti-Human IL-12 (p40/p70)
BV421 Mouse Anti-Human IL-12 (p40/p70)

Two-color flow cytometric analysis of IL-12 (p40/p70) expression in stimulated human monocytes. Human peripheral blood mononuclear cells (PBMC) were preincubated (2 hr) with Recombinant Human IFN-γ (Cat. No. 554617/554616; 10 ng/ml). Lipopolysaccharide (LPS; Sigma, Cat. No. L-2654; 1.0 μg/ml) and BD GolgiStop™ Protein Transport Inhibitor (containing Monensin) (Cat. No. 554724) were then added to the IFN-γ-primed cells which were further cultured overnight.

       The cells were harvested, washed with BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656), stained with APC Mouse Anti-Human CD14 antibody (Cat. No. 555399/561383/561708), and fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655). The cells were then permeabilized and stained in BD Perm/Wash™ Buffer (Cat. No. 554723) with either BD Horizon™ BV421 Mouse IgG1 κ Isotype Control (Cat. No. 562438; Left Panel) or BD Horizon BV421 Mouse Anti-Human IL-12 (p40/p70) antibody (Cat. No. 565023; Right Panel) using BD Biosciences Intracellular Cytokine Staining protocol. Two-color flow cytometric contour plots showing the correlated expression patterns of IL-12 (p40/p70) (or Ig Isotype control staining) versus CD14 were derived from gated events with the forward and side light-scatter characteristics of intact monocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

C8.6

The C8.6 antibody reacts with human IL-12 p40 monomers, homodimers, and p70 heterodimers, but not p35 subunits. The immunogen used to generate the C8.6 hybridoma was the purified p40 subunit of human IL-12. The C8.6 antibody is a neutralizing antibody and has been reported to strongly inhibit three different biological activities of IL-12 (i.e., IFN-γ induction), mitogenic effects on PHA blasts, and enhancement of NK cell-mediated cytotoxicity. C8.6 has been shown to immunoprecipitate IL-23.

The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
