Flow cytometry (Routinely Tested)
0.5 mg/ml
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 biotin under optimum conditions, and unreacted biotin was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  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.

The GR20 monoclonal antibody specifically binds to CD119, the α chain of the interferon γ (IFN-γ) receptor. This receptor is expressed by mouse leukocytes, endothelial, and epithelial cells, but not by mature erythrocytes.  GR20 mAb recognizes an epitope (susceptible to certain fixatives) in the ligand-binding site of the receptor.  It can block the binding of mouse IFN-γ; therefore, it can inhibit IFN-γ .mediated effects including the activation of mouse macrophages for tumor cell killing.  IFN-γ has been reported to induce the expression of Ly-6A/E antigen on cell lines and normal B lymphocytes, and the GR20 antibody is capable of inhibiting the IFN-γ.induced expression of Ly-6A/E on the mouse B lymphoma line A20. The binding of the GR20 antibody to CD119 is inhibited by IFN-γ.  This antibody reportedly does not have any agonist effect.

Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
