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

ELISA: For detection of mouse IgE by sandwich ELISA, this antibody may be used as the detection antibody at ~ 2 µg/ml coupled with purified rat anti-mouse IgE antibody (clone R35-72) (Cat. No. 553413) as the capture antibody.  Purified mouse IgE (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.

Mouse IgE ELISA protocol

I.   Coat with capture antibody:

1.   Dilute the purified rat anti-mouse IgE capture antibody (clone R35-72) (Cat. No. 553413) to ~ 2 µg/ml in coating buffer. Add 100 µl per well to an enhanced protein-binding ELISA-grade plate (e.g., BD Falcon™ Cat. No. 353279). Investigators are encouraged to to determine the optimal antibody concentration for their use. Titrations between 1-8 µg/ml are suggested.

2.   Shake plate to ensure all wells are covered by the capture antibody solution.

3.   Cover the plate and incubate for 1 hour at 37°C or overnight at 4°C.

4.   Wash the plate 3X with PBS/Tween. For each wash, wells are filled with 200 µl PBS/Tween and allowed to stand at least 1 minute prior to aspirating or dumping. As a final step, tap plate on paper towels to remove excess buffer.

II.  Blocking:

1.   Block the plate with 200 µl blocking buffer per well.

2.   Cover the plate and incubate at room temperature for 30 minutes.

3.   Wash the plate 3X with PBS/Tween, as in described section I, step 4.

III. Apply standards and samples:

1.   Leave column 1 of the plate as blank wells (i.e., no antigen added at 100 µl per well consisting of blocking buffer only). Use columns 2 and 3 for duplicates of the standard at 100 µl per well. Dilute the purified mouse IgE standard (Cat. No. 557079, 553481 or 557080) in blocking buffer.  Dilutions should range in a series of 8 two-fold dilutions, in blocking buffer, starting at 0.5 µg/ml. Use the remaining columns to add samples of interest at various dilutions in blocking buffer at 100 µl per well.

2.   Cover the plate and incubate for at least 1 hour at room temperature or overnight at 4°C.

3.   Wash the plate 3X with PBS/Tween, as in section I, step 4.

IV.  Incubation with detection antibody:

1.   Dilute the biotinylated rat anti-mouse IgE antibody (clone R35-118) (Cat. No. 553419) to ~ 2 µg/ml in blocking buffer. Add 100 µl per well. Investigators are encouraged to to determine the optimal antibody concentration for their use. Titrations between 1-8 µg/ml are suggested.

2.   Cover the plate and incubate at room temperature for 1 hour.

3.   Wash the plate 6X with PBS/Tween, as in section I, step 4.

V.  Add avidin- or streptavidin-horseradish peroxidase (Av-HRP or SAv-HRP):

1.   Dilute Av-HRP (Cat. No. 554058) or SAv-HRP (Cat. No. 554066) as recommended for the product (e.g 1:1000) in blocking buffer. Add 100 µl per well.

2.   Cover the plate and incubate at room temperature for 30 minutes.

3.   Wash the plate 6X with PBS/Tween, as in section I, step 4.

VI.  Add substrate and develop:

1.   Thaw substrate (ABTS) buffer within 20 minutes of use. Add 11 µl of 30% H2O2 (Sigma-Aldrich, Cat. No. H1009) to 11 ml substrate buffer and vortex. Immediately add 100 µl per well and allow to develop at room temperature for 20-30 minutes. Color reaction can be stopped by adding 50 µl per well of SDS/DMF Solution (optional).

2.   Read the plate at 405 nm.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources 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.

R35-118

The R35-118 clone has been reported to react specifically with mouse IgE of Igh-C[a] and Igh-C[b] haplotypes. It has been reported not to react with other Ig isotypes.

This antibody is routinely tested by ELISA analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Biotin
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.
