Mouse IgG2B Isotype Control Summary

Recognizes the E-tag peptide. No background staining was detected by immunohistochemistry on a variety of tissues.
Monoclonal Mouse IgG2B Clone # 73009
Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant protein with a C-terminal E-tag (aa sequence GAPVPYPDPLEPR)
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Negative control for immunohistochemistry or immunocytochemistry experiments. Use at the same concentration as the detection antibody.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

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.

Mouse IgG2B Isotype Control
By Anonymous on 05/20/2018
Application: B/N Sample Tested: Breast cancer cells Species: Human

We used this as an Isotype control for our Endothelial Chemotaxis Assay experiments. Conditioned Medium from Breast cancer cells mixed with IgG2B Isotype Control was used to compare Conditioned medium containing cytokines (IL6, IL8, IL1B)
and VEGF-A (IgG2B) neutralization antibody cocktail.
