Product Description

Description: The monoclonal mouse IgG1 K immunoglobulin is useful as an isotype control. Applications Reported: This mouse IgG1 isotype control has been reported for use in surface and intracellular flow cytometric analysis, immunohistochemistry, immunocytochemistry, immunoprecipitation and immunoblotting (WB). Applications Tested: Mouse IgG1 K Isotype Control has been tested by flow cytometric analysis of normal human peripheral blood cells and mouse spleen cells. It should be used at the same concentration as the experimental antibody. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered. The isotype of a primary antibody and the application it is being used in 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 u
