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 optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.  More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).

Product Notices

  1. This antibody was developed for use in flow cytometry.
  2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.

The 114 monoclonal antibody specifically binds to mouse CD212 (the β1 subunit of IL-12Rβ1), originally termed IL-12Rβ, of the mouse IL-12 receptor complex. The IL-12Rβ1 subunit associates with a β2 subunit to form a heterodimeric IL-12 receptor complex. Each one of the IL-12R subunits exhibits low affinity for IL-12, but in combination, they bind IL-12 with high affinity. The IL-12Rβ1 subunit interacts primarily with IL-12 p40 whereas the IL-12Rβ2 binds both to IL-12 p40 and IL-12 p35.  IL-12Rβ1 is required for high affinity binding of IL-12 but IL-12Rβ2 is required for signaling. IL-12Rβ1 has more recently been described to bind IL-23, a heterodimer formed of the p40 subunit from IL-12, and p19. The cytoplasmic regions of the β1 and β2 subunits contain the box1 and box2 motifs found in other cytokine receptors such as gp130, LIFR and G-CSFR. IL-12Rβ1 are primarily expressed by activated T cells and NK cells. Experiments with IL-12Rβ1 deficient mice have shown that IL-12Rβ1 is necessary for mouse T and NK cell responsiveness to IL-12 p75. The 114 antibody was generated by immunizing IL-12Rβ1 deficient mice of (129 x BALB/c)F1 background with mouse Ba/F3 cells that were stably transfected with IL-12Rβ1.

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.

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.
