Western Blot Detection of Human IgG<sub>3</sub>by Western Blot. View Larger

Detection of Human IgG3by Western Blot. Western blot shows lysates of purified human IgG1(negative control), purified human IgG2(negative control), purified human IgG3, and human purified human IgG4(negative control). PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human IgG3Monoclonal Antibody (Catalog # MAB10122) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for IgG3at approximately 240 kDa (as indicated). Human IgG (Catalog # MAB1101) is shown as a loading control.This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Background: IgG3

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.
