BD Pharmingen™
Rat (QC Testing)
Mouse SJL IgG2a, κ
Pooled rat IgG1
ELISA (Routinely Tested), Flow cytometry (Tested During Development)
0.5 mg/ml
Aqueous buffered solution containing protein stabilizer and ≤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.

Recommended Assay Procedures

For the sandwich rat IgG1 ELISA, biotinylated mAb RG11/39.4 is optimal for detection with purified anti-rat IgG1 mAb B46-2 (available by special order) for capture. Biotin-conjugated RG11/39.4 mAb may be used as a secondary reagent in immunofluorescent staining RG11/39.4 antibody is effective for detection of cell-surface or intracellular Ig by immunofluorescent staining with flow cytometric analysis. For flow cytometric detection of intracytoplasmic IgG1, we recommend FITC-conjugated RG11/39.4 mAb (Cat. No. 553892). For immunohistochemical staining, we recommend the use of biotinylated anti-rat IgG1/2a mAb G28-5 in our special formulation for immunohistochemistry, Cat. No. 550325.

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.

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.
