20 µl
Aqueous buffered solution containing BSA and ≤0.09% sodium azide.

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 R-PE under optimum conditions, and unconjugated antibody and free PE 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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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. Please refer to for technical protocols.

The 2B6 monoclonal antibody specifically recognizes the Interleukin 12 Receptor beta 2 subunit (IL-12Rβ2). IL-12Rβ2 serves as the signaling subunit that combines with CD212 (Interleukin 12 Receptor beta 1 subunit/ IL-12Rβ1) to form the functional receptor for IL-12. The IL-12Rβ2 is expressed on T cells and NK cells. IL-12R is a glycoprotein member of the hemopoietin receptor superfamily and is related to gp130, the granulocyte-colony stimulating factor (G-CSF) receptor and leukemia inhibitory factor (LIF). IL-12 is an immunomodulatory cytokine produced mainly by antigen presenting cells (APC) and plays a role in promoting Th1-type responses and cell mediated immunity. It stimulates proliferation of T cells and NK cells, enhances lytic activity of lymphokine activated (LAK) cells and cytolytic T cells (CTL).

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
