Rat IgG2b kappa Isotype Control (eB149/10H5), 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
• Rat IgG2b is a protein-coding gene that encodes for the immunoglobulin G2b (IgG2b) subclass of rat antibodies
• IgG2b is a major subclass of rat immunoglobulins that plays a crucial role in the immune response by neutralizing pathogens and promoting opsonization
• Rat IgG2b is commonly used in research applications, such as in immunohistochemistry, flow cytometry, and Western blotting.
