Biotin Rat Anti-Mouse IgE
Down Arrow Up Arrow

BD Pharmingen™
Igh-7; immunoglobulin heavy chain 7 (heavy chain of IgE)
Mouse (QC Testing)
Rat LOU, also known as Louvain, LOU/C, LOU/M IgG1, κ
Mouse IgE (pooled)
ELISA Detection (Routinely Tested)
0.5 mg/ml
Aqueous buffered solution containing ≤0.09% sodium azide.


Store undiluted at 4°C. 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.


Sandwich ELISA: Biotin Rat Anti-Mouse IgE may be used at ~ 2 µg/ml as the detection antibody coupled with Purified Rat Anti-Mouse IgE (Cat. No. 553416) as the capture antibody.  Researchers are strongly advised to titrate each reagent over a range of concentrations (e.g 1-8 µg/ml) for optimal results.  Purified Mouse IgE κ Isotype Control (Cat. No. 557079, 553481, or 557080) may be used as the ELISA standard.  Alternatively, the BD OptEIA™ Mouse IgE ELISA Set (Cat. No. 555248) is offered as a convenient sandwich ELISA product that is easy-to-use and may be used for the quantitation of soluble mouse IgE.


  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at

The rat anti-mouse IgE antibody (clone R35-72) reacts specifically with mouse IgE of the Igh-C [a] and Igh-C [b] haplotypes. It has been reported not to react with other Ig isotypes. Detection with the rat anti-mouse IgE antibody (clone R35-72) of surface immunoglobulin on IgE-secreting hybridoma cells has also been reported.

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.
