Species Reactivity
The specificity of this antibody was confirmed by direct ELISA on mouse IgG2B monoclonal antibodies, and it does not cross-react with IgG1, IgG2A, IgG3, IgM, IgA, or IgE antibodies. By flow cytometry, this isotype-specific secondary antibody detects primary antibodies of the mouse IgG2B isotype, and does not detect primary antibodies of mouse IgG1, IgG2A, or IgG3 class.
Monoclonal Rat IgG1 Clone # 332723
Protein A or G purified from hybridoma culture supernatant
Cocktail of mouse IgG2B and IgG3
Supplied in a saline solution containing BSA and Sodium Azide.
Allophycocyanin (Excitation= 620-650 nm, Emission= 660-670 nm)


Recommended Concentration

Background: IgG2B

R&D Systems offers a range of secondary antibodies and controls for flow cytometry, immunohistochemistry, and Western blotting. We provide species-specific secondary antibodies that are available with a variety of conjugated labels.

Our NorthernLights fluorescent secondary antibodies are bright and resistant to photobleaching. We are currently offering secondary antibodies recognizing mouse, rat, goat, sheep, and rabbit IgG as well as chicken IgY. These reagents are available with three distinct excitation and emission maxima, making them ideal for multi-color fluorescence microscopy.
