Mouse IgG2b kappa Isotype Control (eBMG2b), Super Bright™ 600, eBioscience™, Invitrogen™

Description

• 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 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
• Mouse IgG2b is a subtype of immunoglobulin G antibody that is produced by B cells in response to an antigen
• It is the third most abundant IgG subtype in the serum and plays a crucial role in the adaptive immune response
• Mouse IgG2b is composed of two heavy chains and two light chains, and it is involved in opsonization, complement activation, and antibody-dependent cell-mediated cytotoxicity
• It is also involved in the regulation of immune responses, including the activation of T cells and the inhibition of B cell activation
• Mouse IgG2b is widely used in research and diagnostic applications, including ELISA, Western blotting, and immunohistochemistry
• It is also used in therapeutic applications, such as immunotherapy and vaccine development.
