Preparation And Storage

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.

Recommended Assay Procedures

For the sandwich mouse IgG1, G2a, G2b, G3, IgM, IgA, and IgE ELISA, Biotin Rat Anti-Mouse Ig, λ1, λ2, & λ3 Light Chain, cocktailed with Biotin Rat Anti-Mouse Ig, κ Light Chain, (Cat. No. 559750) is optimal for detection with any of the following anti-mouse Ig isotype-specific mAbs: Purified Rat Anti-Mouse IgG1, (Cat. No. 553440); Purified Rat Anti-Mouse IgG2a, (Cat. No. 553387); Purified Rat Anti-Mouse IgG2b, (Cat. No. 553392); R40-82 [available by custom order]; Purified Rat Anti-Mouse IgM, (Cat. No. 553435); Purified Rat Anti-Mouse IgA, (Cat. No. 556969); Purified Rat Anti-Mouse IgE, (Cat. No. 553413) for capture, respectively.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. 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.
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  4. Please refer to for technical protocols.

The R26-46 antibody reacts specifically with mouse Igs bearing λ1, λ2, or λ3 light chains. It does not react with κ light chain or heavy chain. Detection of surface immunoglobulin on Ig λ chain-secreting hybridoma cells has been demonstrated with R26-46 mAb.

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.
