BD Pharmingen™
Mouse (QC Testing)
Rat SD, also known as Sprague-Dawley (outbred) IgG1, κ
Mouse IgG2b κ secreted by MPC-11 plasmacytoma
ELISA (Routinely Tested), Flow cytometry (Tested During Development)
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.

Recommended Assay Procedures

ELISA: This antibody has been tested by ELISA (2 µg/ml). For the sandwich mouse IgG1, G2a, G2b, G3, IgM, IgA, and IgE ELISA, biotin-conjugated mAb 187.1 (cocktailed with biotin-conjugated anti-mouse Ig λ1, λ2, and λ3 light chain, R26-46 mAb, Cat. No. 553433) is optimal for detection with anti-mouse Ig isotype specific mAbs (A85-3, Cat. No. 553445; R19-15, Cat. No. 553387; R12-3, Cat. No. 553392; R2-38, Cat. No. 553404; II/41, Cat. No. 553435; C10-1, Cat. No. 556960; C10-3, Cat. No. 556969; R35-72, Cat. No. 553413) for capture, respectively.

Immunofluorescent staining and flow cytometry: Biotinylated 187.1 mAb may be used as a primary or secondary reagent in immunofluorescent staining. For flow cytometric detection of intracytoplasmic Ig, κ light chain we recommend FITC-conjugated mAb 187.1 (Cat. No. 550003).  

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 187.1 monoclonal antibody specifically binds to kappa light chains of mouse immunoglobulins. The 187.1 antibody does not react with mouse λ1 or λ2 immunoglobulin lights chains or mouse immunoglobulin heavy chains.

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.
