Isotype controls

Isotype controls are a type of negative control designed to measure the level of non-specific background signal caused by primary antibodies. The background signal is often the result of immunoglobulins binding non-specifically to Fc receptors present on the cell surface. For example, antibodies raised in mice may bind to some human cells regardless of the test antibody specificity, in a manner related to the isotype of the antibody being used. In these cases you need an isotype control of the same isotype as the test antibody to provide a relevant control for non-specific binding.

Isotype control antibodies

We offer a range of isotype control antibodies that match our primary antibodies, allowing customers to select the appropriate control for their own experimental system.
