Scientific Data

Western Blot Detection of Human IgM antibody by Western Blot. View Larger

Detection of Human IgM by Western Blot. Western blot shows lysates of human serum, monkey serum, mouse serum and rat plasma. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Human IgM Monoclonal Antibody (Catalog # MAB9435) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for IgM at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Simple Western Detection of Human IgM antibody by Simple Western<sup>TM</sup>. View Larger

Detection of Human IgM by Simple WesternTM. Simple Western lane view shows lysates of human serum, loaded at 0.2 mg/mL. A specific band was detected for IgM at approximately 100 kDa (as indicated) using 5 µg/mL of Rabbit Anti-Human IgM Monoclonal Antibody (Catalog # MAB9435). This experiment was conducted under reducing conditions and using the 12‑230 kDa separation system.

Human IgM ELISA Standard Curve. Human IgM protein was serially diluted 2-fold and captured by Rabbit Anti-Human IgM Monoclonal Antibody (Catalog # MAB9435) coated on a Clear Polystyrene Microplate (DY990). Rabbit Anti-Human IgM Monoclonal Antibody (MAB94351) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (DY998) followed by Substrate Solution (DY999) and stopping the enzymatic reaction with Stop Solution (DY994).

Detection of IgM in Human Tonsil. IgM was detected in immersion fixed paraffin-embedded sections of human tonsil using Rabbit Anti-Human IgM Monoclonal Antibody (Catalog # MAB9435) at 3 µg/ml for 1 hour at room temperature followed by incubation with the HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008) or the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC003). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane of B cells.

Background: IgM

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.
