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’s 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.
Host Species: Mouse
Isotype: IgG1
Immunogen: Rat thymocyte membrane glycoproteins
Formulation: 500 ug purified isotype control antibody (1mg/mL) in PBS and no preservative
MA5-18095 is negative on all human cells and cell lines tested. This antibody recognizes a rat cell surface marker, and therefore cannot be used as a negative control in this species. This product is a Low Endotoxin formulation, <0.01 EU/ug. For FACS analysis, use 10ul of the suggested working dilution to label 1x10^6 cells in 100ul.
