Scientific Data Images for Human IgG4 Antibody
Detection of IgG4by Western Blot.
Western blot shows lysates of purified human IgG1(negative control), purified human IgG2(negative control), purified human IgG3(negative control), and human purified human IgG4. PVDF membrane was probed with 2 µg/mL of Rabbit Anti-Human IgG4Monoclonal Antibody (Catalog # MAB98951) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for IgG4at 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.
Human IgG4ELISA Standard Curve.
Recombinant Human IgG4protein was serially diluted 2-fold and captured by Rabbit Anti-Human IgG4Monoclonal Antibody (Catalog # MAB98951) coated on a Clear Polystyrene Microplate (Catalog # DY990). Rabbit Anti-Human IgG Monoclonal Antibody (Catalog # MAB11012) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).Applications for Human IgG4 Antibody

Background: IgG4
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.
