Recommended Assay Procedures

C38-2 is useful as a standard in a mouse IgE sandwich ELISA.

MOUSE IgE ELISA PROTOCOL

Notes:  In most cases, coating the plate with primary mAb at 2 µg/ml, 100 µl per well and detecting with the biotinylated secondary mAb at 2 µg/ml, 100 µl per well yields a very satisfactory signal. However, for optimal signal, researchers should titrate each mAb over a range of concentrations (e.g., 1 - 8 µg/ml). Incubation times are recommended conditions for optimal sensitivity.

I. Coat with Capture Antibody:

1. Dilute the purified anti-mouse IgE capture mAb (Cat. no. 553413, clone R35-72) to 2 µg/ml in coating buffer. *See Solutions section below. Add 100 µl per well to an enhanced protein-binding ELISA plate (eg, BD Falcon™ ELISA Plates, BD Labware Cat. no. 353279).

2. Tap plate to ensure all wells are covered by 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 Section I, Step 4, of this protocol.

III. Apply Standards and Samples:

1. Leave column 1 as blank wells (ie, no antigen added, 100 µl per well blocking buffer only). Use columns 2 and 3 for duplicates of the standard, 100 µl per well: dilute purified mouse IgE standard (Cat. no. 557079, clone C38-2; or Cat. no. 553481, clone 27-74) or mouse IgE standard (Cat. no. 557080, clone C48-2) in a series of 8 two-fold dilutions, in blocking buffer, starting at 0.5 µg/ml. Use the remaining columns to add samples at various dilutions in blocking buffer, 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, of this protocol.

IV. Incubation with Detection Antibody:

1. Dilute biotinylated anti-mouse IgE (Cat. no. 553419, clone R35-118) to 2 µg/ml in blocking buffer. Add 100 µl per well.

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, of this protocol.

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) 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, of this protocol.

VI. Add Substrate and Develop:

1. Thaw substrate (ABTS) buffer* within 20 minutes of use. Add 11 µl of 30% H2O2 (Sigma, 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 50µl 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.
  4. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

C38-2

The C38-2 antibody is specific for the hapten trinitrophenyl (TNP). The immunogen, TNP-KLH, is not expressed on human, mouse, or rat cells. In the absence of specific binding, this antibody may bind non-specifically to Fc receptors. The immunoglobulin from clone C38-2 was selected as an isotype control following screening for low background on a variety of mouse and human tissues.

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

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
