产品详细信息Concentration may vary slightly from lot-to-lot, see lot-specific datasheet for exact concentration.This antibody has been successfully used in Western blot, IF, ICC, IHC, IP and FACS applications.Antibody Specificity: This antibody reacts with the heavy chains on mouse IgG but not with the light chains on most mouse immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins or against mouse IgM. However, this antibody may cross-react with immunoglobulins from other species.Fluorophore: Fluorescein-5-isothiocyanate (FITC-isomer 1)Amax = 492 nm; Emax = 520 nmFluorophore/Protein: 7.5 µg/mg; 2.8 moles FITC per mole IgGRestoration and Storage: Store product at 2-8°C until opened. Restore with 1.1 mL distilled water (1.5 mg/mL after restoration). Centrifuge product if it is not completely clear after standing for 1-2 hours at room temperature. To judge clarity, draw product into a pasteur pipette. Product may be stored for several weeks at 2-8°C as undiluted liquid. After dilution, do not use for more than one day.To extend the shelf-life of this product, add an equal volume of glycerol to make a final concentration of approximately 50% glycerol and store at -20°C.Country of Origin: USA靶标信息IgM (Immunoglobulin M) is expressed intracellularly during the early stages of B lymphopoiesis, and then on the surface of more mature B cells in the bone marrow and peripheral B cells. The isotype of a primary antibody and its application can result in background staining. Primary antibody background noise can be caused by binding to Fc receptors on target cells; by non-specific interactions with cellular proteins, carbohydrates, and lipids; or by cell autofluorescence. Isotype control antibodies can act as negative controls to help differentiate non-specific background signal from specific antibody signal because they have no relevant specificity to a target antigen. While isotype controls are most commonly used in flow cytometry, they are also useful in other applications such as chromatin immunoprecipitation (ChIP), immunohistochemistry, and gel shifts. Isotype controls should match with the primary antibody species and isotype so that the level of specific staining by the primary antibody may be accurately determined. If using directly labeled primary antibodies, the isotype control works best if conjugated with the same label as the test antibody.

数据

Mouse IgG Fc Secondary Antibody (31555) in IFImmunofluorescence analysis of Rabbit anti-Mouse IgG Fc Secondary Antibody, FITC conjugate was performed using MCF-7 cells stained with Cytokeratin 19 (RCK108) Mouse Monoclonal Primary Antibody (Product # MA5-12613). The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, blocked with 1% BSA for 1 hour and labeled with Mouse primary antibody (1:250 dilution) for 3 hours at room temperature. Rabbit anti-Mouse IgG Fc Secondary Antibody, FITC conjugate (Product # 31555) was used at a concentration of 1µg/mL in phosphate buffered saline containing 0.2 % BSA for 45 minutes at room temperature, for detection of Cytokeratin 19 in the cytoplasm (Panel a: green). Nuclei (Panel b: blue) were stained with DAPI in SlowFade® Gold Antifade Mountant (Product # S36938). F-actin was stained with Rhodamine Phalloidin (Product # R415, 1:300) (Panel c: red). Panel d represents the composite image. No nonspecific staining was observed with the secondary antibody alone (panel f), or with an isotype control (panel e). The images were captured at 60X magnification.
