Product Summary for Rat F(ab)2 IgG (H+L) PE‑conjugated Antibody


Rat IgG heavy and light chains


Detects rat IgG primary antibodies in immunofluorescent assays. After purification by affinity chromatography, this antibody was adsorbed to eliminate mouse cross-reactivity and the IgG fraction was further digested with pepsin to generate F(ab')2 fragments which have reduced interactions with cell surface Fc receptors.

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.
