• Species Reactivity

  Rat

• Specificity

  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.

• Source

  Polyclonal Goat IgG

• Purification

  Antigen Affinity-purified

• Immunogen

  Rat IgG heavy and light chains

• Formulation

  Supplied in a saline solution containing BSA and Sodium Azide.

• Label

  Phycoerythrin

Applications

• Recommended    
  Concentration

  Sample

• Flow Cytometry

  Designed for use as a secondary developing reagent in immunofluorescent assays, such as flow cytometry, where the primary antibody does not have a fluorescent reporter, is of rat origin, and is of IgG class. The recommended concentration is 10 μL/10    ⁶ cells.

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.
