Product Specific Information

PA5-33181 is suitable for use as a negative control for the measurement of non-specific binding of mouse monoclonals of isotype IgG1 and IgG2a in human tissues in a dual labelling technique using FITC and R-Phycoerythrin fluorochromes. This antibody contains a monoclonal mixture of FITC-conjugated Mouse IgG1 RPE-conjugated Mouse IgG2a.

Reconstitute with 0.5 mL of distilled water. After reconstitution, store product undiluted at 4ºC in the dark.

For FACS analysis, use 10 µL of the suggested working dilution to label 1x10^6 cells in 100 µL.

Target Information

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.
