Human (QC Testing)
Mouse IgG2a, κ
Flow cytometry (Routinely Tested), Blocking (Reported)
0.2 mg/ml
V C045
Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

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. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Assay Procedures

The antibody from clone Mik-β2 has been reported to inhibit dose-dependently the [125]I-IL-2 binding to YTS cells, which express the β chain alone, with a 50% binding inhibition at 3 mg/ml. Please note that this application is not routinely tested at BD Biosciences Pharmingen.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  4. 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 Mik-β2 monoclonal antibody specifically recognizes the 75 kD β subunit (p75) of the IL-2 receptor (IL-2Rβ). Cell surface IL-2Rβ molecules are expressed by T cells, B cells, monocytes, myeloid precursors, NK cells, and LGL. Together with the α subunit (p55, CD25) and the common γ subunit (CD132; γc subunit of the IL-2R, IL-4R, and IL-7R), the IL-2Rβ molecule forms a high-affinity, signaling receptor complex for IL-2 which can be expressed by activated T and B lymphocytes. Alternatively, some cell types, such as NK cells and myeloid cell populations, coexpress IL-2Rβ molecules and γc subunits to form intermediate-affinity, signalling receptor complexes for IL-2.

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.
