Sheep IgG Alexa Fluor® 488-conjugated Antibody Summary

Serum was obtained from naive (non-immunized) sheep.
Polyclonal Sheep IgG
Protein A or G purified
Supplied in a saline solution containing BSA and Sodium Azide.
Alexa Fluor 488 (Excitation= 488 nm, Emission= 515-545 nm)


Recommended Concentration
Negative control for use in conjunction with R&D Systems antibodies. This isotype control has been derivatized with a quantity of fluorochrome that matched the F/P (fluorochrome/protein) ratio of R&D Systems specific polyclonal antibodies. The recommended concentration is 5 μL/106 cells.

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.

Scientific Data

Detection of Sheep IgG Control by Flow Cytometry C2C12 mouse myoblast cell line was stained with Sheep Anti-Mouse AHR Alexa Fluor® 488-conjugated Antigen Affinity-purified Polyclonal Antibody (Catalog # IC6697G, filled histogram) or Sheep IgG Alexa Fluor® 488-conjugated Isotype Control Antibody (Catalog # IC016G, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: IgG

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.
